Study on Crack Propagation of a Bearing Inner-Ring under Cyclic Loading

Abstract:

The performance of bearing has great influence on mechanical components and fatigue is one of the most important failure modes. However, the occurrence of crack is inevitable in the process of manufacture and usage. Research on characteristics of crack propagation is an important supplement and development to the traditional fatigue analysis method and test. The FE model of a bearing inner ring with a semielliptical crack is established in ABAQUS to carry out further analysis of crack propagation. The crack propagation characteristics with different initial crack size are analyzed and the energy changing law during crack propagation has been investigated under cyclic loading though FE calculation. The results provide valuable guidance for further study on fatigue crack propagation of bearings.
