Finite element model for stress state analysis of deep groove ball bearings with defects

Abstract

In the framework of Industry 4.0, new specific or improved methods for monitoring and prediction of operational conditions of machine elements are required. Ball bearings are among the elements with high impact on safety and reliability of mechanical systems operation. Hence, the development of accurate methods for their working conditions monitoring is one of the important tasks within this framework. In this paper, the development of 3D Finite Element Model for deep groove ball bearings with defects on ring races is described in detail and its place in the new monitoring methods is discussed. Special attention is paid to the modeling of contact finite elements and selection of FEA parameters for fast and secure convergence during non-linear calculations. The stress analysis of contact zones with defects and influence of variable defect dimensions are presented, also.
