Study on Probability Optimization of the Design for Diaphragm Clutch

The effects made by tolerance ranges of size parameters of diaphragm springs on the characteristics of loads and intensity are discussed in detail, the mathematical model of diaphragm springs for optimum design is set up, and constraint conditions are confirmed by applying probability statistics method ,then the program for probability optimization is developed. With a certain diaphragm spring as an example for simulating calculation,based on the comparison and analysis of pass rates before and after the optimization,it can be concluded that tolerance ranges of main sizes of diaphragm springs are the critical factors to influence the level of pass rate, so tolerance ranges should be chosen properly. Calculating results show that probability optimization method can promote the design level of diaphragm springs,make it possible to control the quality of products and reduce the production costs.
