| Abstract: |
| The mechanical property of rubber material was simulated by using Van der Waals equation，and the fatigue life of rubber bush was calculated under vertical jitter conditions and lateral turn with loading based on the accurate fitting of the stiffness.The durability of the rubber bush for the rear axle of torsion beam was effectively assessed by using the maximum principal tensile strain，strain energy density，and the relationship curve of the strain energy density and service life of rubber specimen. |
