Abstract: Based on the sport utility vehicle (SUV), the system scheme and function of the rear suspension air spring were designed, and the air spring was designed according to the coil spring technical parameters of rear suspension. Then, the finite element model of air spring is established by using the nonlinear finite element analysis software Abaqus, the simulation results of air spring stiffness was proved to be effective by bench test. Finally, the rear axle air suspension system was mounted on the sport utility vehicle (SUV). The subjective evaluation test was carried out on the SUV vehicle with rear air spring suspension, the results showed that the vehicle equipped with the rear air suspension system was superior to the traditional suspension prototype in terms of riding comfort and trafficability.
