Contact Stress FEM Analysis of Deep Groove Ball Bearing Based on ANSYS Workbench

The 3D nonlinear contact model of a deep groove ball bearing was established in ANSYS Workbench software. With the reasonable setting of the boundary conditions,the contact stress and deformation are calculated in Static Structural (ANSYS) by using the finite element method,and the contact stress and deformation of the inner ring, the outer ring and the rolling elements were obtained. Furthermore, the computational values are consistent with the Hertz values. The results show that solving the bearing contact problem with ANSYS Workbench software is feasible and it coincides with the stress and deformation of the actual situation. The FEM results provide reference for the design,optimization and failure analysis of rolling bearings and have practical engineering value.
