To acquire accurate finite element model of torsion beam suspension, a correction method is put forward, which is based on stiffness test of torsion beam suspension,and which modifies the FE model of the torsion beam suspension by adjusting the particle mass at the shock absorbers and the density of the beam which is used to simulate spring. The stiffness characteristic calculated with FE model before and after modification is compared with that obtained by test, which shows that the proposed method can improve the speed and precision of model calculation effectively.
