[Abstract]:Spring is one of the important mechanical parts, as a mechanical element with elastic force, it is widely used in various mechanical and electrical devices. With the progress of mechanical technology, more and more kinds of springs are required. The traditional spring design theory can not meet the needs of the increasingly competitive spring industry. With the development of computer technology, computer aided design technology, optimization technology and finite element analysis technology, these modern design methods have been applied more and more in spring design practice. In this paper, the cylindrical helical spring is taken as the research object. The optimum design, parametric modeling and parametric finite element analysis of the spring are carried out based on MATLAB,Pro/toolkit and APDL language. Firstly, the optimal design theory and the optimization design method of cylindrical helical spring are introduced, and the mathematical model of optimal design is established. With the help of the optimization toolbox of MATLAB and the graphical user interface development environment GUIDE, the optimization design system of cylindrical helical spring is created, which realizes the high efficiency of the optimization design of cylindrical helical spring and facilitates the design. Secondly, the general method of Pro/E secondary development using Pro/Toolkit programming technology is studied, and the spring model is created by using parameterized modeling method and Program technology. With the help of Visual C integrated environment of Pro/Toolkit, a parameter driver is developed. The parametric modeling of spring is realized, and the efficiency of spring modeling is improved. Finally, the second development technology of ANSYS is introduced. The finite element model of spring is established by using ANSYS's internal command, APDL language and parameterization technology, and the parametric analysis of spring is realized by using the secondary development technology of ANSYS. The finite element analysis spring is used to model, the calculation is simple, convenient and fast. The research work of this paper has realized the optimization design, parametric modeling and analysis of cylindrical helical spring, which is of great significance to the application and popularization of modern design methods in spring design.
