In this paper, the orbital forming analysis of automotive wheel bearing was performed by finite element method. Commercial software MSC.MARC was used and 2-dimensional axisymmetric element was applied. Deformation, stress, and force direction were calculated and investigated for the design aspect. To verify the reliability of this study, experiment was carried out and compared with analysis results. The experiment results showed good agreement with the analysis results.

Tire, wheel, wheel bearing, knuckle, brake, and suspension dominate vehicle steering performance. Stiffness of wheel bearing, which is a part of corner module, is important property to affect steering performance. Most of wheel bearings are used for angular contact ball bearing. In general, stiffness of angular contact ball bearing depends on ball contact angle. In this study, analysis model was developed, which can consider the stiffness behavior with ball contact angle change. MSC. MARC was used for the numerical analysis with nonlinear and contact analysis. Stiffness behavior was investigated for the small straight drive loading condition. To verify the reliability of this study, experiment was carried out and compared with analysis results. The experiment results showed good agreement with the analysis results.

Automotive wheel bearing is one of important parts that transmits engine power into wheels and supports vehicle weight. In this study, strength analysis and design optimization are carried out for wheel bearing. First, for cracked bearing strength analysis is performed to calculate the stress distribution. Next, optimization is performed in order to minimize the stress of cracked region. From the result, we assumed that the crack cannot be occurred.
