Abstract:

The theoretical analysis and experimental research for the cushion process of a high-speed hydraulic cylinder with a piston cushion structure was introduced. The whole cushion process was divided into two stages, the orifice throttle cushion and the tapered gap throttle cushion. A mathematical model of the cushion process was established, based upon the mathematical model, the influence of the structural parameters on the cushion velocity and the pressure of cushion chamber was analyzed. The experiment for the cushion process of two sets of prototypes with different structural parameters was done. The theoretical and experimental results are consistent with each other basically.

Key words: hydraulic system, high-speed hydraulic cylinder, cushion structure, cushion process
