【Abstract】 For the nonlinear characteristics of Hydraulic-Pneumaticsuspension system stiffness, the linearization of its elastic force was equivalent by statistical linearization methods. Based on the 2-DOF vehicle model, the response characteristics and probability distribution of the suspension system vibration displacement were obtained. In that way, the design basis and calculation method of the suspension system height limit were proposed. The simulation results show that the design basis and calculation method have high accuracy and engineering application value, which can provide theoretical basis for the actual height limit design of hydraulic-pneumatic suspension.更多还原
