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.

The torsion beam axle 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 the characteristics of rear suspension in the initial stage of the design process. The dynamic characteristics estimation of the torsion beam axle is performed using FEM, dynamic simulation and is verified through the real test. In this study, the natural frequency and roll stiffness of the torsion beam axle were predicted by FEM, and the FE model was validated by the comparison with test data. This study presents a result of dynamic and durability analysis for performance estimation of the torsion beam axle.<br/>
