A design formula of single throttle slice thickness was established with the computation for?mulas of opening valve pressure and. throttle slice deformation. The design method and principle of su?perposition slice were founded using the computation formulas of equivalent thickness and stress. The conditions of opening valve were studied, and the computation formula of adjustment gasket was giv?en. The design-formula of throttle aperture of hydro- pneumatic spring was established according to the relationship between pressure and flux. On basis of this, the influence factors of valve parameters were analyzed. The parameters of hydro-pneumatic spring were designed, the equivalent thickness of super?position throttle slice and the characteristics and stress intensity of opening valve were validated, and the performance test was conducted for the hydro-pneumatic spring. The experiment and analysis re?sults show that the superposition throttle slices has the effect on the valve parameters of hydro-pneu?matic spring.
