This research analyzed stress at contact surface of hub and hub bearing, and aim to simplified selling of design, optimization of manufacturing and maintenance. Experiment analysis made test piece model from automobile hub, and used stress freezing method. It analyzed stress of automobile hub with different contact condition by changing R of load point reconstructed structure of hub bearing. Numerical analysis used finite element method. It analyzed stress of an analytical model identical with experiment analysis by not reproducing contact condition. From both parties, it calculated stress concentration factor of contact with automobile hub and hub bearing. As a result, it proposed the approach to formulation and quantification.
