Finite Element Analysis of Self-Lubricating Joint Bearing Liner Wear

The finite element model of sliding wear is established by applying finite element theory according to Archard wear model. The general program is developed by ANSYS Parametric Design Language (APDL). The wear analysis of self-lubricating joint bearing liner is carried out. The simulation and the experimental results are very consistent with the relative error being 6.38%. In the simulation, the concept of the wear step length is introduced, and the method of moving boundary key point of the liner region in the model is used to describe the material removal process. The parametric modeling is used to refine the liner layer and then divide the mesh, and then the internal meshes distortion caused by boundary point change is solved. Meanwhile, the appropriate wear step length is used to improve the computational efficiency and accuracy. The results show that the finite element method can predict the sliding wear from the viewpoint, which provides a practical tool for practical engineering wear design.
