Brinell phenomenon observed on wheel bearing of vehicle represents the dent generated on raceway due to rotating balls. In this paper, numerical analysis is performed to analyze the Brinelling by using finite element method. Commercial software of MARC is used and plastic and contact analysis are carried out to compute the behavior of the raceways and balls. In order to get the accurate stress-strain relationship, tensile test is performed. To verify the reliability of this study, the depth of Brinell is measured by experiment and compared with computational analysis results.

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.
