摘　　要：立柱是液压支架主要部件,新国标中提出对液压支架立柱进行动载过载试验,为满足要求,对液压支架立柱动载过载试验系统进行研究。采用理论计算、液压原理设计、三维建模等方法研究立柱动载过载试验系统,利用蓄能器组快速释放功能,实现在短时间内释放大量高压液体,使被试立柱安全阀打开溢流,完成试验。设计的系统可在30 ms内达到动载过载试验的流量及压力要求。Hydraulic support column is the important part of hydraulic support, we researched of hydraulic support column impact testing system in order to meet with new national standard requirements. The text has studied of hydraulic support column impact testing system with theoretical calculation, principle of hydraulic system designed, three dimensional modeling. The accumulator can quick release a large of high pressure liquid and the safety valve overflows. The system can achieve the requested flow and pressure in the 0.03 seconds.
