The vehicle’s driving system consists of many components. A hub is one of them. This study is on designing a new driving system, especially a hub. A hub connects a drive shaft to a knuckle and supports all forces exerted on wheel against to knuckle. Thus the structural analysis of the hub is very important. If the stress value does not meet the target level, the design must be changed. In this paper, a shape optimization method is adopted to design of the hub from the point of the stress analysis. Auto_dv is used for generating shape perturbation vector and MSC/Nastran is used as the optimizer

Vibration fatigue analysis of TPMS housing and antenna is performed in the frequency domain. It is well known that TPMS (Tire Pressure Measurement System) is a very important part in vehicle safety. In this study. we procedure mode analysis. modal frequency response analysis and vibration fatigue analysis. As a result, the TPMS housing and antenna is safe in the vibration environment, and the critical location is the curved position in the antenna.
