Currently pneumatic technology plays important role in modern industrial technology, and pneumatic cylinders are more generally taken as actuators, the operation speed of which is gradually improved, while cushioning device with good performance guaranteeing the pneumatic cylinder can stop in stable and slow speed status at the end of travel. Simulation and experiments analysis finds that the pneumatic cylinders with pressure relief valve used to manually regulate the cushioning properties in small adjustment range, easily lead to the oscillation of piston speed. A novel cushioning device is furtherly proposed to achieve better cushioning property, in which the clearance volume of cushion chamber and the spring compression of pressure regulating valve can be regulated according to the variation of piston speed. And then the AMESIM numerical model of high speed pneumatic with novel cushioning device is developed to perform simulation when the piston speed varied in 3.0~3.7m/s, and the mass of the moving parts in the actuator system is 4kg. The analysis result showed that when the maximum piston speed varies in 3.0 to 3.5m/s, the optimum cushion performance can be achieved by adjusting the clearance volume of cushion chamber, but the maximum piston speed varies in 3.5to 3.7m/s, the spring compression of pressure regulating valve can be regulated to achieve the optimum cushion performance. Furtherly the good cushion adjustment range of novel cushion device is determined through the simulation, which is wider comparing to original pressure relief valve.
