Construction of a Cylindrical Cam Model With Clearance for Wear Study

Zhengzhu ZHOU, Xiaoyi JIN, Xingyu ZHU, Yuyi LIN


Using Solidworks and MATLAB as solid modeling and computation tool, a cylindrical cam model with clearance is developed in this paper. The purpose of such a model is for future study of wear, such as wear pattern and wear rate. The model is based on the reported Achard wear model. It is hoped that the model not only can predict the wear rate and depth of wear, but also serve as a tool to cylindrical cam design, for less wear and longer useful life. Wear depth prediction model established in this paper shows that the wear depth will increase, if the cam rotational speed increases.
