Abstract

Wear is one of the important factors affected on the lifetime of some contacted components in machinery. In the design engineering wear factor is very important to be considered because of its correlation to a design for the long lifetime. There are three types of causal wear away; mechanical, chemical and thermal. One of the type which caused by mechanical is a wear away that happened because of sliding contact system. In this thesis, a commercial finite element software ANSYS is used. Modeling and simulation procedures are proposed with the linear wear law and Euler integration schemes. The Archard’s wear principle was used as an additional calculation beside Finite Element Method (FEM ) analysis. The simulation was modeled as a pin-on-conforming and pin-on-flate static contact and also elasticity steel on steel material without lubrication as elasticity material assumption in this study. The prediction results of FEM were being verified with Saad Mukras’ prediction results. Wear rate was calculated as a function of sliding distance. The results showed that the wear rate increases as the increasing of sliding distance, however, the wear rate decreases due to the increasing of contact area.
