Experimental Investigation of Air Cushion Characteristics in Pneumatic Cylinders
Author(s): 
Pages: 321-324
Year: Issue:  3
Journal: JOURNAL OF BEIJING INSTITUTE OF TECHNOLOGY

Keyword:  气缸气缓冲特性计算机辅助测试;
Abstract: 研究气缸气缓冲特性,建立计算机辅助测试系统.通过调节气源压力和缓冲针阀开度,测试不同工况下缓冲腔及主气路压力、气缸行程以及振动加速度等参数,并分析过缓冲、欠缓冲及最佳缓冲等几种典型的气缓冲特性.实验结果表明:气缸活塞与端盖的机械碰撞是造成振动冲击的主要因素;一些过缓冲过程仍存在机械碰撞,从而造成缓冲效果变差;最佳气缓冲只存在于某些工况.
