Research on Influence of Valve Opening Velocity to Valves Design parameters of Hydro-Pneumatic Spring

Through the relations of throttle pressure with the flux and slice deformation, the analytic formulas of valves parameters design is established. Analyzed the influence of suspension damping raito to the valves parameters, the influence coefficients of valve opening velocity to the valves parameters was founded. With practical example of hydro-pneumatic spring,the valves parameters was designed with the methods of the analytics desgin and influence coefficients, the deigned parameters was validated ,and the performance test was conducted for the designed hydro-pneumatic spring. The experiment and design results show that the valve opening velocity has influence to the valves parameters, the design methods of valves parameters is accurate, and the valve opening velocity influence coefficients is applied for different style vehicle, having importance for hydro-pneumatic spring design.
