摘要
本文通过对液压支架降往过程的仿真，获得了支架液压系统的动态特性。在此基础上，分析了影响支架降柱快慢的各种因素，并探讨了提高降往速度的途径。
By simulating the process of a lowering of leg of powered support, the paper shows dynamic characteris tics of a hydraulic system of powered support,then analyses various factors infecting the speed of lowering leg and discusses some methods for increasing the speed.
