Simulation of wear for a typical revolute joint under periodic load of a gear door lock is implemented with a three-dimension finite element model based on Archard’s wear law. Both the wear of the journal and the shaft of different materials are taken into account. The load and motion of the joint are acquired by the dynamic solution of the mechanism as the inputs of wear simulation. Displacements of the nodes experiencing wear are governed by the user subroutine UMESHMOTION in the finite-element code ABAQUS by which the direction of wear and wear depth are calculated. ALE adaptive meshing technology has been used to maintain a high-quality mesh. An effective adaptive extrapolation method is presented to minimize computational time and keep the accuracy by the processor algorithm. In the last part, the influence of clearances on the simulation of wear is investigated with the developed model.
