Structure, basic working principle, method of damping adjusting and air-chamber volume adjusting for a new type suspension strut consisted of the air spring and the hydraulic shock absorber are introduced in this paper. A gas-liquid coupling dynamic model for the new type suspension strut was established. New front suspension strut of a passenger car was designed, the nonlinear dynamics performance of the strut, main influence factors and gas-liquid mechanical coupling relationship were analyzed by using simulation software. Bench test results indicate that testing results were very close to the simulation results, verifying that the design scheme of the new type suspension strut is feasible and the established gas-liquid coupled model is correct.
