基于MATLAB的膜片弹簧参数对性能影响及优化

根据膜片弹簧载荷与相对轴向变形值的关系，利用MATLAB软件分别对自由状态碟簧的内截锥高度、膜片弹簧钢板厚度、未受力时碟簧部分的大小端半径、压盘加载点半径和支承环加载点半径六个重要特征参数进行分析，总结了各特征参数对膜片弹簧性能的影响；对某型膜片弹簧进行了优化，各参数在优化后提高了离合器的相关性能并延长离合器的使用寿命。

Influence of Diaphragm Spring Parameters on Performance and Optimization based on MATLAB

According to the relationship between the load and the relative axial deformation value of the diaphragm spring, six important characteristic parameters are analyzed by using MATLAB, including the height of the internal truncated cone of the disc spring in the free state, thickness of steel plate, radiuses of large and small end of disc spring part without any force, the radius of pressure plate loading point and loading point of support ring. The influences of characteristic parameters on the performance of diaphragm spring are summarized. The optimization of a diaphragm spring improves the performance of the clutch and prolongs the abrasion limit of the clutch.
