Summary of Graduation Design Fan Wenxuan (I) started from the topic selection of the thesis in 2000 10, and now the thesis is basically completed, from the initial confusion to the present moment. What kind of writing process you have experienced may not be expressed in words, but the final joy still makes people forget the hardships on the way. Perhaps this is my greatest achievement. In recent months, I feel that every day is full of fighting ideas and I have lived a full life. It was not until the final paper was finalized that the big stone in my heart was put down.
At the beginning of October, I decided on the topic of my thesis: analyzing the influence of handiwork on children's skills. When I first received the question, I couldn't start. The tutor asked us to read at least five related documents. In the process of reading, I gradually began to have a spectrum in my heart, so that I had the necessary understanding of the direction and methods of the following papers.
I began to look up information on the internet and in the library, classify the information I got, learn from other people's arguments and add my own views. I began to make an outline, and under the guidance of the teacher, my thoughts gradually became clear. After writing the first draft, I had a preliminary exchange with my teacher, who gave me a lot of opinions and suggestions. The teacher pointed out that my article was too theoretical and there were no substantive proof examples. Therefore, I have a clear direction in the process of revision. I decided to go deep into the kindergarten for a period of experiments. During the period, I benefited a lot and felt deeply, and I had a more comprehensive understanding of young children. I found that at present, in class, many teachers often follow the book, which seriously imprisons children's thinking. Teachers should let children express their ideas in their attempts. So I recorded these questions and began to learn to integrate theory with practice. Don't talk too much.
The completion of the second draft is mainly to consult a large number of relevant materials and documents, and analyze and sort out the materials in detail according to these documents and materials, so as to fully and correctly understand and master the problems to be studied. The experimental method is also adopted. After going deep into kindergarten, the children were divided into manual group and painting group to compare their abilities. After summarizing and analyzing the specific situation in practical activities, the final conclusion is drawn.
In the process of reviewing, I have a deeper understanding of the topic "the influence of handiwork on children's skills", and I realize the important significance of handcraft in education and teaching, and fully realize the common problems in kindergartens at present.
In the process of revising the second draft by the teacher, I obviously found that there were many fewer mistakes and my determination was more firm, so I started to work on the third draft. In the final draft, the key point is to grasp the format. I set up the typesetting step by step according to the format required by the school.
Finally, I finished the final draft as I wished. Like most people, I was confused and anxious, and finally I persisted. I believe where there is a will, there is a way. I understand that persistence is necessary, because writing a paper is a long research process, and it can't be done overnight. Be careful, because the paper deals with words, so you should think carefully and taste any word and sentence. Whether the words are appropriate or not and whether the sentences are fluent or not will affect the final result of the paper. Therefore, I have gained a lot from writing my thesis, which should be helpful to my future work.
When the graduation project is completed, I want to thank my alma mater for training me over the years, and all the teachers for their help, especially my tutor Ms. Miao Xin. She gave me careful care and guidance in the process of writing my graduation thesis. Teacher Miao gave me a lot of encouragement and support from the topic selection to the final completion of the thesis. She carefully revised and corrected the article for me, and often communicated with each other, which made me clearer, so that the paper was constantly improved and perfected.
Here, I would also like to thank my friends, who gave me great help and guidance in the experiment, so that I can successfully complete my graduation thesis.
Thank you for your concern, encouragement and help to all my teachers and classmates.
Time flies, and the sixth week of the next semester of senior year has passed. In the past six weeks, Ren Ren has performed well in his study, life and peacetime training, and his quality has been further improved. At the same time, there are still many shortcomings that need further study and supplement. In order to make a deeper self-evaluation in the summary, it is expounded from the following aspects:
First, study. When it comes to learning, it is no longer a question of whether there are classes, because most people have finished all the courses when they are in junior year. The last problem that many people face in this semester's study is how to successfully complete the graduation project.
The requirements of the school for graduation project are more and more strict, especially in our communication department. Graduation design defense is conducted separately. In order to improve the quality of graduates, batch defense is implemented this year. Students who have failed more than 6 classes so far will reply separately. This requires every student to take this final graduation project seriously.
I started my graduation project after the postgraduate entrance examination last semester. Because the topic selection is difficult and the teacher is strict, I go to the laboratory almost every day. At first, I learned the theoretical knowledge related to Bi Jian. After I understood these theories, I began to read a lot of related papers.
Learn relevant knowledge and processing methods from it. At first, I felt that the difficulty coefficient was large, and many related professional words were new to me, but I was not discouraged, but humbly asked my teachers, brothers and sisters for advice.
Until the problems encountered are thoroughly understood. After a semester of hard work, I finally made substantial progress. Basically mastered several models of partial differential equations in digital image processing.
The next task is to realize these models through programming. So far, these tasks have been basically completed. This graduation project is almost completed. The next step is to carefully sort out the work done during this period and finally complete the design.
Graduation design summary model essay selection (Part III) Graduation design can be said to be an assessment and summary of four years' study and practice in our university, and it is a compulsory course for every college graduate. Not only did we learn a lot of knowledge, but we also explored experience from practice and improved the drawing ability of software. In the process of graduation design, through my own efforts and the guidance of my tutor, I completed my final design internship in this university with a rigorous and realistic spirit.
This design is the first large-scale design practice from theoretical conception to practical engineering demonstration in my university, which makes my understanding of professional knowledge more profound, which is not only a summary of learning, but also a summary of life.
The purpose of this graduation project is to make myself know more about the technology used in sewage treatment, the location of sewage plant, the selection of process flow and parameters of sewage plant, the calculation of process size of sewage treatment structures and other process design calculations, to be familiar with the construction of sewage treatment structures, to improve the ideas and procedures of engineering design, to strengthen the drawing ability of professional software, to be further familiar with the steps and requirements of engineering design, and to lay a solid foundation for engineering design. Achieve the comprehensive application of professional knowledge, improve the ability to analyze, solve and work independently, and lay a good foundation for future engineering and technical work. I carefully wrote the opening report and made the opening defense. In response to the questions and suggestions put forward by the teacher, I adjusted and supplemented the process selection, completed the design and calculation of the process flow of the sewage plant, the plane layout and elevation layout of the sewage treatment plant, and drew the plane profile of each structure.
Because this technology is relatively new and popular, there are many problems in the design process, the selection of design parameters in each process of filter work is not very certain, and the design is not very smooth. Later, under the guidance of the teacher, referring to the existing projects and various parameters, the design and calculation of D-type filter were completed. It is also a problem when drawing the plane cross section of D-type filter, and some parameters are not very clear in the calculation process. But when I encounter problems, I always tell myself to be patient and design rigorously. It took two days to draw the plane section of D-type filter. Other structures are simpler than D-type filters, but it takes a day or two to draw the plane section of each structure. In the process of drawing, I will start with the design drawings of sewage plant, and gradually draw with Tianzheng software. Finally completed the graduation project.
This process is a learning process. In the design process, our junior professional knowledge is only a small part. When we really design, we have to consult a lot of data and have strict requirements on the selection of process parameters. After this graduation project, I learned a lot of knowledge that I had never learned before, and I had a clearer understanding of myself. We take the initial process comparison, structural calculation, drawing of drawings and preparation of instructions very seriously. For example, in the equipment selection of engineering design, we all look for samples from actual manufacturers on the Internet for selection and drawing. We know that graduation design is different from curriculum design. Graduation design is closer to the actual work in the future and should be considered more comprehensively. The design should also be humanized to facilitate the future operation of the sewage treatment plant.
Reduce the risks and troubles caused by poor design. For example, many details of road layout should be fully considered when making the plane layout of sewage plants.
Because it is the first time to contact with actual engineering design, it is also a virtual design process. Due to the limitation of our own level, we have no practical experience in parameter selection and lack of knowledge in civil engineering, electrical installation and geological conditions, so the design result is only theoretically feasible. Although we have theoretical knowledge, whether the result is feasible needs to be verified in future work.
This design also exposed many of my shortcomings, which made me find that it is not a simple thing to do a good job in engineering design. It requires solid professional knowledge and design experience, patience and strong perseverance to complete a relatively perfect design. These are the things that we just graduated and entered the society. In the future work and study, I will strive to improve myself, master more new professional knowledge, further improve my overall quality, better adapt to the rapidly developing modern society, and strive to become an excellent engineer as soon as possible!
Graduation design summary model essay selection (Part IV) Graduation design is a comprehensive practice link in the university for three years. Its purpose is to cultivate the ability to comprehensively apply the knowledge of various courses and to cultivate the ability to analyze and solve problems independently through the design and research of the subject. The graduation design of college students in China should be closely combined with production practice, oriented to the cultivation of professional ability, and should reflect the characteristics of college students.
Under the careful arrangement and guidance of the professor, this graduation project is carried out in accordance with the graduation project work plan from determining the design topic, drawing up the design scheme, the design process to the graduation defense.
First, fully investigate and determine the application-oriented graduation design.
The topic selection of graduation design is the premise to achieve the goal of graduation design and ensure the quality of graduation design. Our graduation project topic is taken from the actual production of the enterprise. This topic can comprehensively apply the professional knowledge that students have learned or the professional skills needed for future work, and achieve the purpose of comprehensive application. It can not only solve the production technical problems that enterprises urgently need to solve, but also cultivate students' professional post ability. It is not difficult, and it is in line with our college students' professional theoretical knowledge level and practical design ability. The workload is appropriate and can be completed within the specified time.
Second, repeatedly demonstrate and determine the design scheme of the parts.
Defining the nature, significance, design content, technical and economic indicators and completion time of the project, determining the correct and reasonable design scheme is the guarantee for completing the design task, discussing with classmates at ordinary times and designing under the guidance of teachers, so as to have a good concept of the project design scheme.
Third, improve the design and prepare for the graduation design defense.
A complete design includes technical documents such as design drawings and design specifications. According to the requirements of the design task book, comprehensively check the design technical data, and carefully modify the drawing errors and design specifications according to the correction of the instructor.
In the process of this graduation project, through my own efforts and the careful guidance of Professor Liu Qingsong, I made good use of the rich library resources of the school and consulted a large number of books, manuals and other materials about mold design and manufacturing, which can better complete the task of this graduation project.
Through this graduation project, I have a certain understanding of the process regulations and process equipment design process of diesel engine body parts, and learned a lot of useful and practical skills. Graduation design is not only a test of previous knowledge, but also an improvement of one's own ability. The main gains and experiences are as follows:
1, learned the method of product design.
The process of product design is a creative labor process, and the product design should be carried out in accordance with scientific procedures, which generally includes the process of subject investigation, drawing up design scheme, overall design, part design, technical data collation, product trial production and improved design. A product must be improved many times before it can be perfect and mature.
2. Improve the comprehensive application ability of all kinds of knowledge.
In the past, the relationship between curriculum design and curriculum knowledge was relatively narrow. This graduation project is to design a complete set of process regulations and process equipment design for diesel engine body parts. To design each part, you need knowledge of manufacturing technology and mechanical design.
3. Consolidate computer drawing ability.
In the past, drawing with CAD only knew the operation of the main instruction. Through drawing a large number of drawings this time, I am more familiar with the operation methods of common instructions in mechanical drawing, and draw complete and correct part drawings with simple and quick methods, so as to better understand the three-dimensional drawing software Solidworks and UG.
4. The ability to collect data and consult manuals has been improved.
Collecting data is the preparation for graduation project. Whether the data is comprehensive and reliable is related to the whole process of graduation design. In the design process, you can consult the manual at any time. Only by collecting useful information extensively can we design better products.
In a word, through the graduation project, we have cultivated our ability to comprehensively apply the theoretical knowledge we have learned, which is of great help to the technical distribution and management of the production line in the future. This is inseparable from the careful guidance of the department leaders and Professor Liu Qingsong. I would like to express my heartfelt thanks here!
Due to my limited knowledge and lack of practical experience, this design must have some shortcomings. Please criticize and correct me, put forward valuable opinions and correct them in time. Diesel engines are widely used in industrial and agricultural production because of their compact design, easy start-up, simple maintenance and advanced technical and economic indicators, and can be used as supporting power for walking tractors, pumps, power stations, transportation and various agricultural and sideline processing machinery and equipment. Engine block is an important part of diesel engine, and fine boring is the most critical process in engine block processing. This process ensures more than 70% of the main technical requirements of the engine block. High machining accuracy is required, especially for the tolerance of the depth of cylinder liner hole of engine block, the tolerance of large-span coaxial hole with the same diameter and balance shaft hole, the tolerance of large cantilever cylinder hole, the verticality between crankshaft hole and cylinder hole, the parallelism between crankshaft hole and balance shaft hole and camshaft hole axis, and the verticality between cylinder liner hole and cylinder hole axis.
Graduation design summary model essay selection (Chapter 5) With the arrival of graduation day, graduation design is drawing to a close. After several weeks of hard work, my graduation project was finally completed. Before graduation design, I think graduation design is just a simple summary of the knowledge I have learned in recent years, but through this graduation design, I find my point of view is a bit too one-sided. Graduation design is not only a test of previous knowledge, but also an improvement of one's own ability. Through this graduation project, I realized that my original knowledge was still relatively lacking. I still have so much to learn. I used to think I knew everything, everything, and I was a little arrogant. Through this graduation project, I realize that learning is a long-term accumulation process, and I should keep learning in my future work and life, and strive to improve my knowledge level and comprehensive quality.
In this graduation project, the relationship between our classmates has been further improved. Students help each other. If there is anything we don't understand, we can discuss it together, listen to different opinions and better understand our knowledge. So I am very grateful to my classmates who have helped me here.
That's all I know. In short, no matter what I have learned, I still can't learn anything. I really find it difficult. It's really hard to start everything, and I don't know how to start. Finally finished, I feel relieved. Another conclusion is drawn: knowledge can only realize its value through application! Some things are thought to be learned, but the real use is two different things, so I think the real use is really learned.
I want to thank my mentor _ _ for his careful guidance and help.
In the design process, through consulting a large number of relevant materials, exchanging experiences with classmates, self-study and consulting teachers, I learned a lot of knowledge and experienced a lot of hardships, but I also gained a lot.
I learned a lot in the whole design, and also cultivated my ability to work independently, and established my confidence in my work ability, which I believe will have a very important impact on my future study, work and life. But also greatly improved the hands-on ability, so that I fully realized the difficulty of exploration and the joy of success in the creative process. Although this design is not very good, what I learned in the design process is the biggest harvest and wealth of this graduation design, which will benefit me for life.
Graduation design summary model essay selection (Chapter VI) As graduation day approaches, graduation design is drawing to a close. After three months of hard work, our group's graduation project was finally completed. As a team leader, I did my duty, and under the guidance of my teacher, I organized my team members to think and explore this topic. Compared with the previous curriculum design, this graduation project has thought a lot, and also exercised my organizational ability and profound understanding of some knowledge, which benefited me a lot. Graduation design is not only a test of previous knowledge, but also an improvement of one's own ability. Through this graduation project, I understand that my original knowledge is relatively lacking, and there are still many things to learn. In the past, teachers thought they knew everything and felt a little arrogant. Through this graduation project, I realized that learning is a process of continuous accumulation. What I knew before was only superficial, which made me know that I should keep learning in my future work and life and try my best to enrich my brain.
This graduation project requires the design of electrical control system for medical pure water treatment. It is very difficult for us to design it ourselves. We can only rely on the works completed by our predecessors and make further breakthroughs on this basis, which is a challenge and a test for us. Therefore, this design process needs to be carried out according to the requirements of the design steps, so as to further master the design operation flow and achieve the purpose of learning.
First of all, I found many problems in this design that have not appeared before. For example, there are many kinds of pumps, and their rated power should be calculated according to the needs, and their functions and functions should be investigated in the drawings. At the same time, we choose contactors, relays, solenoid valves, fuses, thermal relays, indicator lights, signal lights, switches, circuit breakers, pressure relays, liquid level relays, DC power supply devices, conductivity meters, etc. It needs to be screened and further considered before it can be selected. So many of them are not found in our textbooks at ordinary times, and we need to consult a lot of materials, but the materials are not necessarily complete. It also needs the participation and guidance of teachers, and finally it can be found, because each choice is different in application, and it is selected according to different functions and targeted. At the same time, I also learned how to grab pictures with QQ. We didn't grasp it at first, and it looked messy. After the teacher's guidance, I trimmed them and learned to deal with the waste edges, which looked much cleaner. The most important thing is how to deal with hyperlinks in the directory. I didn't know at first that the directory was generated automatically. I manually enter the directory, which is not only invalid, but also messy. After the teacher's in-depth guidance, I finally learned how to automatically generate the directory. All these have made me make continuous progress in my study.
Secondly, there are many problems in the process of drawing with CAD. In the previous CAD class, we only knew that we could finish the task by drawing a complete picture within the scope of drawing, so we followed Ke Ben's painting and ignored the scale design. As a result, the picture drawn is ugly, because the printing needs are not taken into account, the letters and lines are too close together, and the proportion of nodes and lines is asymmetric. The most important thing is that the distance between connecting lines is too large and the period is too small. And I know that with the rapid development of social economy, the influence of water on people's life and production is deepening, and people's requirements for water supply quality and quantity are also increasing. Applying advanced automation technology and control technology to water supply has become a new requirement for water supply. The electrical control system of medical purified water treatment integrates factory power supply and programmable control technology. The system can improve the purity of water system and facilitate medical treatment; At the same time, the system has good energy saving, which is particularly important today when water quality is in short supply. This design adopts PLC-controlled water treatment system, which is logically controlled by PLC. After calculation, the sewage eventually turned into medical pure water.
Only infiltration technology is used in the design, and there are few relevant materials in the usual textbooks. Through the information provided by teachers and the information collected on the Internet and in libraries, we know the principle, salt production characteristics and application scope of reverse osmosis, and know its indispensability in water treatment. The principle of reverse osmosis is a set of water treatment system organized around reverse osmosis membrane. A complete reverse osmosis system consists of pretreatment part, reverse osmosis host, post-treatment part and system cleaning part. It plays an important role in the flow chart of water treatment process. Water can only be used for medical purposes after it has been infiltrated twice. All these tell us to pay attention to the combination of theory and practice. Book knowledge is the theoretical basis, and laying a good foundation is the basic condition for doing a good job. But practical experience is also very important. Theory is the foundation of practice, and at the same time, hands-on practice can enrich theory, and the two complement each other. There is a lot of basic knowledge in design that we haven't understood, which is the result of lack of practical experience. This requires us to master some relevant information and conventional knowledge in order to find and solve problems in time in future applications.
This graduation project not only improved the relationship between our classmates, but also made me learn a lot from them. There will always be problems in the design process. When I can't solve them, I will always ask other students, and they will patiently give me answers. If some problems are not handled well, we will also discuss with each other and actively participate in the discussion to make the problems gradually clear. The relationship between students is also closer in this design, and their friendship is also a step closer.
As the old saying goes, everything is difficult at the beginning. That's true, but after more than three months of hard work, it's finally finished, and I'm relieved. In addition, a conclusion is drawn: knowledge can truly realize its value only through application! Some things are thought to be learned, but the real use is two different things, so I think the real use is really learned. Theory and time are inseparable.
Finally, I would like to thank our instructor, Miss Yang Meifen, for her careful guidance and my classmates who have helped me. In the design process, through consulting a large number of relevant materials, exchanging experiences with classmates and consulting teachers seriously, I learned a lot of knowledge, experienced a lot of hardships, but also gained a lot. I learned a lot in the whole design process. It also cultivated my ability to work independently and established my confidence in my work ability, which I believe will have a very important impact on my future study and work. But also greatly improved the practical ability, so that I fully realized the hardships of exploration and the joy of success in the creative process. Although this design is not very good, what I learned in the process of design is the biggest harvest and wealth of this graduation design, which will benefit me for life!
After four months of hard work, my graduation project was finally completed, but now looking back at the whole process of graduation project, I have a lot of experience, bitter and sweet, bitter and happy, but I enjoy it! Through this graduation project, I feel that the graduation project is just a simple summary of what I have learned in recent years before accepting the task, but through this graduation project, I find that the graduation project is not only a test of what I have learned before, but also an improvement of my ability.
As a student, graduation project is my last assignment. It is not only a comprehensive summary and comprehensive application of the knowledge learned in the school, but also a good start for practical application in the future. Graduation design is a test and summary of learned knowledge, which can cultivate and improve designers' ability to analyze and solve problems independently. It's the last comprehensive homework I handed in at school.
The graduation time is approaching day by day, and the graduation design is drawing to a close. After continuous efforts, my graduation project was finally completed. Before graduation design, I thought graduation design was just a general summary of what I had learned in recent years, but when I really faced graduation design, I found that my ideas were basically wrong. Graduation design is not only a test of previous knowledge, but also an improvement of one's own ability. Through this graduation project, I realized that my original knowledge was too theoretical, and I felt at a loss in the face of individual topics. I still have so much to learn. I used to think I knew everything, everything, and I was a little arrogant. Through this graduation project, I realize that learning is a long-term accumulation process, and I should keep learning in my future work and life, and strive to improve my knowledge level and comprehensive quality.
In short, no matter what you learn, you can't learn anything. It's really difficult. It's really hard to start everything, and I don't know how to start. Finally finished, I feel relieved. Another conclusion is drawn: knowledge can only realize its value through application! Some things are thought to be learned, but the real use is two different things, so I think the real use is the real learning.
Thanks to my tutor, Mr. Tang, for his careful guidance and teachers' help. In the design process, through consulting a large number of relevant materials, exchanging experiences with classmates, self-study and consulting teachers, I learned a lot of knowledge and experienced a lot of hardships, but I also gained a lot. I learned a lot in the whole design, and also cultivated my ability to work independently, and established my confidence in my work ability, which I believe will have a very important impact on my future study, work and life. But also greatly improved the hands-on ability, so that I fully realized the difficulty of exploration and the joy of success in the creative process. Although this design is not very good, what I learned in the design process is the biggest harvest and wealth of this graduation design, which will benefit me for life.
