Research on the Ideal Cushion Method of Pneumatic Cylinder

Abstract:

In the situation of high-speed or heavy load, pneumatic cylinders usually generate cushion failure like collision or rebound, so that the key question to be solved for the cylinders is cushion. In order to obtain a better cushion method, the paper used the ideal cushion characteristic curve of hydraulic cylinders for reference; and throttling area equation, temperature equation, flow rate equation and motion equation were established. By building the simulation module in Matlab/Simulink, the rule of throttling area approaching to the ideal cushion curve was found, which provide theoretical basis for the design of cylinders cushion devices.
