Research on Modeling and Characteristics of Two-Stage Pressure Hydro-Pneumatic Spring

Abstract:

The structure and principle of the two-stage pressure hydro-pneumatic spring were introduced. the physical and dynamic vehicle models with it were established under AMESim environment. Static characteristic curves of the two-stage pressure hydro-pneumatic spring were drawn. A single chamber hydro-pneumatic spring was used to compare the suspension dynamic travel and body vertical acceleration of the vehicles equipped with two-stage pressure hydro-pneumatic spring. The results show that two-stage pressure hydro-pneumatic spring can effectively enhance the vehicle riding comfort by decreasing body vibration.
