In this paper,taking the vehicle powertrain anti-torsion mount as the research object,the stress and strain curves of its rubber material were first tested,and then the Ogden hyperelastic constitutive model was used to simulate its mechanical performance.Based on the accurate simulation of its stiffness characteristics,the finite element model in Abaqus was calibrated.Based on the theory of strain fatigue of rubber material,the ε-N fatigue curve of its rubber material was determined by experiments and its rig fatigue life was calculated and optimized.The rubber material fatigue curve has been corrected according to the durability test results of the rubber structure,then its fatigue life on the Vehicle driving endurance test is forecasted eventually.
