The influence of the design parameters of the hydraulic shock absorber on the vibration damping effect is studied to provide the design method of the hydraulic shock absorber.Taking the inertial passage-decoupling membrane hydraulic shock absorber used in the Audi 10 0 sedan as an example, The physical model of the hydraulic shock absorber is deduced and the mathematical expressions of the dynamic stiffness Kd and the lag angle θ are derived to analyze the influence of the main design parameters on the dynamic stiffness and the retard angle of the shock absorber. The dynamic characteristics of the shock absorber have the greatest impact. The parameters of the inertial passage cross-sectional area and the length of the inertial passage also have an important influence on the dynamic characteristics of the shock absorber.
