Finite Element Simulation Of Hybrid Ceramic Angular Contact Ball Bearings

Along with the evolution of the ceramic material, the hybrid ceramic ball bearings had been used in more and more extensive. But the design for the ceramic ball bearing got far behind its'using in our country. The article utilized the FEA(Finite Element Analysis) on the contact problems of hybrid ceramic angular contact ball bearing, and investigated the method and technical points on the contact problems.At first the article analyzed a correspondingly simple problem that a plane contact with sphere. At the same time, Hertz theory results had been received. Compared to the Hertz theory results and correlative experiment results, the FEA results were reasonable.Based on above discuss, this article established the FEA models for hybrid ceramic angle contact ball bearings. In the models, the main component of bearings ware predigested properly. The boundary conditions approached to actual work conditions and parameters specially for contact analysis were discussed. As a result, contact stress and strain of static analysis were obtained. Compared to contact theory in elastic mechanics for bearings, the FEA results were evaluated and the difference between them was discussed.Some elementary simulations for friction behavior in bearings were investigated in the last sect of the paper. These accomplishments ground the further research of FEA simulation for hybrid ceramic ball bearings.The paper found an available method to solve contact problems of hybrid ceramic angle contact ball bearings using ABAQUS and provided academic basic for design and analysis of hybrid ceramic ball bearings analogous to angle contact bearings, as well as reference to study an improvement of bearings process.
