In this paper, deformation analysis is performed in order to check the interference fit for inner ring of automotive wheel bearing pack-seal. Commercial software MSC. MARC is used and material nonlinear, geometric nonlinear and contact analysis are carried out to get a more accurate results. We considered the design tolerances between inner ring and outer steel of pack-seal and got the allowable interference range of inner ring. From this result, we found that the interference between inner ring and spindle may occur in the worst design case.

Automotive wheel bearing is an essential component of the vehicle and transmits engine power into wheels and supports vehicle weight. As comfortable ride has recently been the common interest, the stiffness of bearing which affects the steering performance becomes significant. In this study, the program BSAP was developed to carry out the stiffness analysis by designer easily and quickly. BSAP has three templates; CATIA template, AFC template, and Report template. In CATIA template, 3D analysis model was generated from the CAD model by eliminating useless fillets and holes and assigning heat treatment parts. Material property, boundary conditions and loadings were applied and analysis was performed in AFC template. Finally, analysis results were reported automatically in Report template. Bearing stiffness analysis was performed by using the BSAP. To verify the reliability of BSAP, the analysis results were compared with experiment results. They showed good agreement with the experiment results.
