The mesh matching method is proposed for clearance error and non point contact problem caused by mesh discretization in the finite element analysis rolling bearing. Firstly,the mesh matching and the importance of the matching to contact calculation in finite element analysis is expounded. Secondly,the mesh matched 3- D model of ball bearing is analyzed. Finally,the mesh matching and compacting is analyzed quantificationally based on a simplified model of bearing contact problems. The results show that,the mesh non-matching causes larger error for arcs and cambered surfaces contact problem,the effect of mesh matching is obvious; the mesh matching and compacting can significantly improve the accuracy of analysis for Hertz contact problem; a better analysis precision can be achieved when the mesh matched and non- compacted rolling bearing model is used. The study has a certain guiding significance for accurate finite element modeling and analysis of rolling bearing.
