The Seat Back latch system is used in the vehicle rear seat back. This latch system must be guaranteed the high strength to prevent seat back folding on the rear impact situations. And this latch system must be satisfied with both the reinforced safety regulations and the profitability of components supplier. So the latch core parts should be optimized within limited design form. To develop this latch core parts, it is necessary to estimate of the characteristics of the proper materials, heat-treatment and the design process from the FEM. In this study, The strength of variable core design were measured by FEM, the optimized design was verified by real test. The result of this study present the seat back latch core part design and it could be used production.

The torsion beam axle type is widely used in the rear suspension for small passenger cars due to low cost. good performance. etc. 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 torsion beam axle is performed using FEM. dynamic simulation and is veri fied the real test. In this study. the natural frequency and roll stiffness of the torsion beam axil: were measured by FEM. and the reliability of the FE model was evaluated according to the comparison of test data. This study presents a unique method for the finite element modeling and analysis of the torsion beam axle. The results of the FEA were verified using test data.
