A study on wear characteristic for oscillating disc cam mechanism using GA

In the cam mechanism, the problem of surface fatigue or wear becomes more severe at contact point between cam and roller follower. The more fatigue or wear is, the less the lifetime is. As well as it leads to loss of engine performance, so to reduce the surface fatigue or wear is the primary problem to solve. In this paper, a general polynomial function developed by Thoren, Engemann, and Stoddart (TES) with real values of exponents is selected and genetic algorithm (GA) is used to decrease the surface fatigue by minimizing the wear rate proportional factor (WRPF) since they vary directly. Therefore, an attempt of this paper has been made to minimize the maximum value of WRPF using GA as the optimization program. And the results show that the minimum the maximum WRPF can be lowered approximately 10% in this paper.
