Testing Research of Accumulator Performance in the Hydro-pneumatic Suspension of a Vehicle

Taking a 2.5 liter accumulator with hydro pneumatic suspension in a CXP 1032 crane made in Germany as the research object and taking both the overall road simulative test bed and the control equipment made by the Schenck Company of Germany as the testing instrument, the structure performance and mechanism are theoretically clarified and the variation of gas states are obtained. This illustrates the accumulating and releasing process of a 2.5 liter accumulator in a 32 t crane in the real condition. The preliminary volume and pressure of accumulator would directly affect the stiffness performance of the hydro pneumatic suspension in a vehicle.
