Two-Dimensional Finite Element Analysis on Running-in of Elastic-Plastic Rolling Contact.

The running-in of rolling contact between a rigid cylinder against a deformable rough surface is simulated by finite element method in this paper. Two-dimensional model of rough surface is employed in the simulation by considering the elastic-plastic material with strain hardening behavior. The topographical changes of the rough surface due to running-in of rolling contact are observed for the applied load or interferences. A relatively high load is applied so that it operates in the elastic-plastic deformation regime. The running-in phase, indicated by the high asperity truncation, is found within the first two cycle of the rolling contact. After the third cycle, the steady state deformation occurs. A comparison between the running-in of rolling contact and the repeated static contact for the same model and is also presented. [ABSTRACT FROM AUTHOR]
