There are several types in rear suspension of passenger cars. The torsion beam suspension type is widely used for small passenger cars due to simplicity and lightweight To develop the torsion beam axle, it is necessary to estimate of the characteristics of rear suspension from the design process. The characteristics estimation of the tubler torsion beam axle is preformed using Finite Element Analysis and apply to shape optimization. In this study, static analysis, roll stiffness of the torsion beam axle were predicted by Finite Element Analysis.

Recently, The Hydroforming technology has recognized general technique in manufacture industry. Especially automotive industry, It has applied to increase strength, and decrease weight, cost and part number. The rigid axle suspension type is widely used for truck and bus in commercial vehicles due to simplicity. To develop the hydroforming rigid axle, it is necessary to estimate of the characteristics of front suspension from the design process. In this study, the characteristics estimation of the hydroforming rigid axle is preformed using Finite Element Analysis and apply to shape optimization.

Recently, automotive industry has applied to increase strength and decrease weight, cost and part number. A hot stamping process has been implemented to increase the strength of passenger car body parts and to reduce not only the weight of parts but also the number of work process. This paper is concerned with the crash analysis of Rear module model in order to compare the effectiveness between hot stamping model and conventional model.
