Abstract

A test platform based on interconnected hydro-pneumatic suspension was set up to research the pressure characteristic of damping hole of this kind suspension. A series of experiments on damping holes of different diameters were carried out, and the pressure on both sides of damping holes were recorded. The discharge characteristic of pipes, cylinders and joints in this test platform are analyzed. A mathematical and simulation model of this platform was established using knowledge of fluid mechanics. Various parameters of all hydraulic subsystems were analyzed. The mathematical model and the simulation model were verified by experiments result. These models can be used to research interconnected hydro-pneumatic suspension.
