Influence of elastic modulus to valves designing parameters of hydro-pneumatic spring

Through the relations of throttle pressure with the flux and slice deformation,the analytic design formulas of valves parameters of hydro-pneumatic spring is established.Analyzed the influence of elastic modulus to the valves parameters,the influence coefficients of elastic modulus to the valves parameters is founded.With practical example of hydro-pneumatic spring,the valves parameters is designed with the methods of the analytics desgin and influence coefficients,the deigned parameters is validated,and the performance test is conducted for the designed hydro-pneumatic spring.The experiment and design results show that the elastic modulus has influence of the valves parameters,the analytic design methods of valves parameters is accurate,and the elastic modulus influence coefficients is applied,it has importance for hydro-pneumatic spring designing.
