气缸气缓冲特性的实验研究

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 ;

Modeling and Simulation of the Characteristics of Pneumatic Cushion Cylinders

The analysis of the characteristics of the cushion process of the pneumatic cushion cylinder is presented, and the nonlinear model of pneumatic cushion cylinders is built in the form of nonlinear differential equations. Besides, through the simulation of the pressure in the cushion chamber, the characteristics of the pneumatic cushion cylinder are obtained, which helps to understand the performance of the pneumatic cushion cylinder and improve or design the better cushion structure.
