1 guide to interim report

The main data of this graduation project is to select a constitutive model suitable for rubber hyperelastic materials through ABAQUS software on the basis of experimental measurement. During this period, the completed work and progress, existing problems and solutions, and the later work arrangements are as follows:

I. Completed work and progress

1. Learn to search for articles related to the subject through the school website, find and read relevant literature on the constitutive model of rubber hyperelastic materials, and understand the research background and benefits of the subject.

2. Learn the finite element software ABAQUS under the guidance of the tutor, complete the basic example, then establish the finite element model according to the existing rubber uniaxial compression experiment, import the experimental data into ABAQUS model for fitting evaluation, finally determine the appropriate constitutive model and calculate the corresponding parameters.

3. Complete the translation of English documents related to graduation project. Through the translation of documents, I have a preliminary understanding of digital image analysis.

Second, the existing problems and solutions

Through the study of ABAQUS software, we have a better understanding of the constitutive model of hyperelastic materials, but there are still some problems such as unskilled use of software and weak ability to deal with problems independently. We must strengthen our study and use ABAQUS software independently and skillfully in the future.

Third, the next work arrangement

Week 8 and Week 9: Study the paper format and matters needing attention, and then write and generate the first draft of the paper for the tutor to review.

Weeks 10 and 11: Revise the thesis according to the tutor's guidance, pass the tutor's assessment, and finally generate the final graduation thesis before the defense.

Iii. Existing Problems and Solutions

In the design process, I deeply feel the lack of some information and knowledge, especially the selection and verification of injection molding machines and the calculation of some institutions. The information is either cursory or general, and there are few professional and detailed discussions. But in the end, we decided to put aside differences while reserving differences, take its uniqueness as the focus of this design, and choose infrastructure for design.

In addition, I want to read more information about mold design to make the designed mold more applicable. At the same time, it is necessary to strengthen communication with the instructor and deepen the understanding and understanding of this design. In a word, I believe that I will continue to work hard, and under the careful guidance of my tutor, I can quickly and effectively carry out the next design process and successfully complete the graduation design work.

Fourth, the later work arrangements

1. It takes two weeks to draw the part drawing and the overall assembly drawing of the main parts of the mold.

2. Three-dimensional modeling of main parts was completed in two weeks by using ProEngineer drawing software.

It takes two weeks to sort out relevant materials, write graduation thesis and prepare graduation defense.

Guiding opinions on the interim report of the thesis 4

1, graduation design progress

After the graduation project, I got a preliminary understanding of the definitions and uses of nanofibers and electrostatic spinning devices through the previous materials, and further carried out solution configuration, spinning device construction and electrostatic spinning experiments. In this process, I have been doing experiments constantly. In the process of doing the experiment, I found the problems, constantly made comparative analysis, and then revised the relevant parameters reasonably. Aiming at some problems in the experiment, the second reference comparison experiment was carried out. In the course of the experiment, I am also conducting related performance tests. At present, the spinning task required in the task book has been basically completed. The next task is to assemble the battery and test its performance. Although the workload of the later sequence is small, it takes a long time, so we should seize the time.

2. Phased results have been achieved.

1-3 weeks: consult and translate materials, and submit opening questions, internship reports and related translations; 4-6 weeks: according to the experimental scheme designed in the paper, the feasible process parameters are analyzed and the preparation process is improved; Improve the experimental data, do pre-experiments, and build an electrostatic spinning device;

7-9 weeks: prepare fiber felt by spinning in the laboratory, prepare battery cathode material by oxidative carbonization, and measure battery assembly and other related processes.

3. Existing problems (or difficulties encountered)

There is a problem:

The structure of electrostatic spinning machine device is complex;

The spinning dope is unstable, which is easy to block the nozzle or interrupt spinning, and is not suitable for felting;

Spinning experiment is dangerous, which requires the use of high voltage electricity and liquid and gas supply devices;

Solution:

With the help of teachers and classmates, a relatively perfect electrostatic spinning device was built.

The experimental materials were changed, the suitable solution concentration was explored, the conditions for preparing the solution were improved, and a filter device was installed on the nozzle.

All experimental devices are packed with insulating paper, and the metal decoration is isolated with plastic. Try to use good quality ones.

High-quality and high-safety product structure experimental device.

4, the next step plan

10 ——12 weeks: explore the appropriate electrostatic spinning process parameters, and adjust the spinning solution concentration, voltage, receiving distance, gas volume, flow rate, temperature and humidity according to the diameter of the spun nanofibers. Assembling and measuring electricity

Performance indicators related to the pool.

13- 14 weeks: processing experimental data, writing graduation thesis and preparing defense;

15 weeks: defense.

Week 16: Improve the paper.

5, experimental harvest and experience

Through nearly a month's experiment, I have gained a lot, not only consolidating my professional knowledge, but also exercising my practical potential. In addition, I also learned about the potential of consulting relevant materials through the internet and retrieval, and at the same time deepened the friendship between students and improved teamwork.

Of course, in the course of the experiment, we will inevitably encounter some difficulties and setbacks. At this time, we all try our best to solve problems by ourselves without bothering the teacher, which also teaches us the potential to handle and solve problems independently. Sometimes when we encounter things that we don't understand or understand, several of our classmates will discuss them with each other. Until these problems are finally solved, several of us will feel extremely happy and happy because of the solution of the problems. But sometimes we will encounter professional problems, and if we can't solve them, we will look through them and inquire about relevant information. Through these, we have also increased a lot of knowledge and broadened our knowledge. During the experiment, the teacher also gave us a lot of careful help and guidance, so that we would not be at a loss sometimes. It is under the guidance of the teacher that our experiment can be carried out smoothly and orderly. I really appreciate the teachers' guidance.

On the whole, we really benefited from the experiment. The graduation project really gave us all a good opportunity to exercise, not only learned knowledge, but also exercised the potential of experiment. Therefore, I am very grateful for this opportunity, and I am also grateful to the teachers for their concern, help and guidance. I will continue to work hard to do the experiment well, and finally write a satisfactory graduation thesis and graduate smoothly, which will draw a satisfactory end for my college life!
