Aiming at the road spectrum simulation test rig of the front subframe of a car, the design of the test rig fixture based on multi-objective Optimization and the simulation prediction of the fatigue life are introduced in detail. Our engineers optimize the stiffness of the test rig by using the finite element software, so that the stiffness of the car body can be accurately simulated, and the force characteristics of the subframe on the test rig are the same as on the real car, thus the validity and accuracy of the bench test results are ensured. The fatigue test of the subframe is simulated by using the fatigue life software FEMFAT and the fatigue life of the subframe is predicted, greatly reducing the test time.
