摘　　要：针对工作面中液压支架立柱密封性差的问题,通过建立立柱控制回路活塞组合密封和鼓形密封摩擦力模型,应用AMESim软件对2种不同密封方式的液压缸给定相同的矩形波信号、斜坡信号以及阶跃信号,对大缸径双伸缩立柱活塞组合的密封响应特性进行分析。同时通过泄漏测试以及关于流固耦合的仿真分析,说明密封圈泄漏量都是随着压力的增大而增大。证明活塞组合密封液压缸在稳定性、响应时间、静态误差等方面相对鼓型密封具有较好优越性。According to the poor sealing characteristics of the column in the working face, the characteristics of the hydraulic cylinder, the slope signal and the step signal of the hydraulic cylinder with two different sealing methods. The leakage test and fluid solid coupling simulation show that the leakage increases with increasing pressure. It proves that the hydraulic cylinder has advantages over drum seal in stability, response time and static error.
