Experience of engineering graduates: As the graduation day approaches, the 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 day by day, and people's requirements for water 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!
Experience of engineering graduates 2. After graduation design is completed, you also need to write a graduation design summary report, which is a summary and a reminder for yourself. Because of the completion of graduation project, it not only marks a perfect end for four years of college, but also lays a good foundation for future life.
The topic of my graduation project is "Preparation of bidding documents for Xinxiangyuan 1# building project". I chose this topic because I think it can link up my knowledge of four years in college and play a good review role. As the saying goes, reviewing the past and learning new things will have a good effect on future work.
The beginning is to write the opening report. Under the guidance of the instructor, I filled out my graduation project step by step through the template given by the teacher. In addition, I also collected relevant academic papers, core journals, books and so on. Write papers through the internet and libraries. After writing for two weeks, I finally finished the opening report.
Next, according to the arrangement of graduation design task book, I began to draw drawings. According to the requirements of the Student Affairs Office, I need to draw six drawings. Including four machine paintings and four hand-drawn paintings. When I first started painting, I had to review what I said before about painting, so that I could work better. In addition, according to the relevant specifications provided by the teacher, I found out the points for attention in drawing and how to really draw architectural drawings. On the basis of the preliminary work in place, the drawing will progress faster after it starts. * * * After two weeks, I finished drawing.
According to the arrangement of the task book, after reading the drawings and drawing them, the next work is the calculation of engineering quantity and computer calculation. This is the key project of the whole graduation project, because it is the concentrated expression of our professional knowledge. Before doing this work, we must read the book "Engineering Cost" again, and have a comprehensive understanding of the valuation norms and how to correctly calculate the engineering quantity. In the process of calculation, Mr. Wang often comes to our classroom for guidance, which can answer our questions in time and lay the foundation for our calculation work. In addition, when calculating steel bars, we need some calculation rules and some atlases, and Mr. Wang also provides them to us as much as possible, so that we can smoothly carry out the graduation design. In the process of calculating the package price by computer, Mr. Wang provided us with a set of pricing standards for decoration projects in Jiangsu Province, which solved many problems for us.
After the calculation of engineering quantity is completed, the next work is to prepare the construction organization design, commercial bid and technical bid. Some of my main steps are modified according to some templates. Some data needed are some data tables generated by arbitrage.
The final work is foreign language translation and drawing output. I found an academic paper online and then translated it with translation software.
After all the above work is done, I will wait for the teacher's approval, and then modify it myself until I meet the teacher's requirements. This is a continuous reciprocating process.
In the whole process of graduation thesis design, I learned the attitude and mentality that I need to do anything. First of all, I learned to be meticulous in my study, and I can't underestimate any problems and deviations that appear. I should solve it in the right way, have patience and perseverance in the process of doing things, and don't give up when encountering difficulties. I can find a way to solve the problem as long as I persist. Learn to cooperate with others in your work and listen to others' opinions carefully, so that you can get twice the result with half the effort.
First of all, I want to thank my tutor, Mr. Wang Dongmei, and my classmates and friends around me for their help and their valuable opinions and suggestions. In addition, I want to thank all the teachers who taught me knowledge during my college days. It was your careful teaching that gave me a good understanding of specialized courses, which is also the basis for the completion of the thesis.
Engineering graduates realize that their three or four years of college life are coming to an end. Through the four-year study of civil engineering, we have cultivated the basic potential of each of us to do architectural structure design independently. Unconsciously, the graduation project is coming to an end, and this half year will be unforgettable.
Graduation design is the last link of students' learning stage, the comprehensive application of basic knowledge and professional knowledge, and a comprehensive process of re-learning and re-improving. This process also cultivates students' learning potential and independent work potential, and the level of graduation design also reflects the comprehensive level of undergraduate education. Therefore, the campus attaches great importance to graduation design and strengthens the guidance and mobilization education of graduation design work.
With the guidance and help of teachers and classmates, I successfully completed this design project-the frame structure design of the teaching building of Xinjiang Pishang Vocational High School. According to the schedule in the task book, I finished my graduation project on time and accurately. In the early stage of graduation design, I reviewed various related textbooks, including structural mechanics, reinforced concrete, seismic design of building structures, foundation design and so on. , and borrowed the relevant design specifications. In the graduation design, we first carried out architectural design. Teacher Tang is mainly responsible for our architectural design guidance and the correction of architectural drawings. The teacher strictly requires everyone to be beautiful and practical until the graphics meet the specification requirements. Then the structural design. Teacher Lu is mainly responsible for structural design. Teacher Lu is serious and responsible. He sees students at least twice a week. When I don't know, the teacher always explains it to us seriously until we all understand. In the graduation project, Qi Xin, a member of our group, worked together and cooperated with each other, giving full play to everyone's team spirit. Near the end of the graduation project, Mr. Lu instructed us to draw the structural drawing, modify all the drawings and sort out the calculation book.
Through this graduation project, I have a further understanding of the knowledge of frame structure. Through this design, I really applied the theory I learned to analyze and solve problems, especially in the concrete frame structure, and at the same time I felt the lack of knowledge and lack of solidity. At the same time, in the process of drawing, I improved my potential of using PKPM software and CAD software. This graduation project has enabled our team to master the knowledge I have learned in recent years more systematically. At the same time, the completion of graduation project will also help my future work.
This position has laid a good foundation.
The end of graduation project means the end of our college life and stepping into the society. Through our own efforts and diligence, I believe we will realize our ideals in the future.
Experiences of engineering graduates. At this time, the graduation project, which lasted for more than a month, is coming to an end, which has benefited a lot. I was really at a loss when I first got this topic. I don't know what to do with this part drawing. Under the guidance of my tutor, I got a clue after several days of careful analysis and investigation of relevant materials. With the comprehensive understanding of the part drawing, the design work is also in full swing. In the design process, I also consulted a large number of course books related to this design, such as mechanical drawing, mechanical design basis, mechanical manufacturing technology, CNC machine tools and so on. In the design process, it is not enough to rely solely on textbooks. I also consulted many reference books and materials about design. In this design, some parts are processed automatically, which improves the production efficiency and quality. Therefore, we can master automatic programming better and lay a more solid foundation for future work.
Special fixture is also considered in the design, which has the advantages of accurate positioning, stable and reliable clamping, convenient operation and low cost. However, there are also corresponding disadvantages: the clamping force needs to be coordinated by experience and control, otherwise either the clamping force is too large, which will cause local deformation of the box, or the clamping force is too small, which will lead to instability and inaccuracy of the workpiece. Both of these conditions will affect the machining accuracy and quality. When tightening the pressure plate, force must be exerted at the same time to ensure the uniform stress on the workpiece and reliable clamping. In addition, the significance is also significant:
1. In this graduation project, we can comprehensively use the knowledge of courses such as NC machine tool processing and machine tool manufacturing technology, and the basic knowledge of courses such as machine tool fixture and NC programming and mechanical manufacturing technology, correctly analyze the positioning of parts processing, and reasonably work out the problems such as clamping, process route and NC programming, so as to ensure the accuracy and quality, productivity and economy of parts processing.
2. The design of furniture and other process equipment will further cultivate students' ability of process structure design and drawing.
3. Through this graduation project, we further strengthened and understood the cad software and NC machining programming, which enabled us to better grasp their characteristics.
4. Learn how to investigate and collect technical data during graduation design and graduation practice, and be familiar with the use and retrieval of technical reference books related to reference books, manuals and charts.
This graduation project is a field test of our promised theoretical knowledge and practical knowledge, which cultivates our ability to comprehensively apply the theoretical knowledge and skills we have learned, analyze and solve problems.
6. Scientifically understand and improve the productivity, economy and sociality of products through the compilation of process regulations and the formulation of process routes.
7. Cultivate our ability to investigate, study, collect charts and data, cultivate our structural design ability and drawing ability, as well as NC automatic machining programming ability; Cultivate our understanding of various processing machine tools, better understand the characteristics and scope of application of various machine tools, so that we can better and more flexibly choose suitable machine tools for processing in the future.
Through this graduation project, I feel the importance of what I have learned, and I also find that my comprehensive application ability of what I have learned is far from perfect. However, I have made some progress in the process of completing this graduation project, so that my knowledge and practical knowledge can be integrated and my problem-solving ability can be improved. At the same time, I also consolidated my knowledge and skills and laid the foundation for my future work and further study.
Through this design, I really think? Knowledge lies in accumulation? 、? Is knowledge endless? Deeply feel your own shortcomings, so as to find problems and solve them, so that the same problems can be solved as soon as possible in the future. Therefore, we must take root in practice and enrich ourselves.
In a word, because my professional foundation is relatively poor, my practical experience is too little, and the combination of practice and theoretical knowledge is not close enough, so there must be many mistakes and shortcomings. Please criticize and correct me. Finally, I sincerely thank you for your patient teaching, as the instructor of my graduation project and the teacher of the university for three years. Thank you! Students, please forgive my previous shortcomings!
