| Abstract: | Pneumatic cushion cylinder is the most common actuator in pneumatic transmission systems. The structure and principle of needle valve cushion and relief valve cushion were introduced. Cushion performance and capacity of absorbing impact were compared by simulation. The results show that relief valve cushion has stronger absorbing capacity and smooth velocity; this advantage is available for high - speed cylinder. The result obtained is helpful for the design and application of pneumatic cushion cylinder. |
