Abstract
The elastic properties of a torsion beam suspension determine the kinematic performance of the suspension. In the design phase, the numerical analysis such as the finite element analysis is usually utilized in order to estimate this suspension performance. However, most automotive designers cannot directly perform this analysis because specific skills are required to achieve sophisticated operation. In this paper, we apply a new concept of CAE, First Order Analysis, to the suspension design in order to overcome this problem. Further, we introduce a design program of the torsion beam suspension based on this concept, and confirm the usefulness of this program using simple examples.
