摘　　要：在保证液压支架初撑力基础上实现快速移架是综采工作面支护的一个难题,通过分析大采高液压支架双伸缩立柱控制系统的工作原理,建立了液压支架升降柱过程的状态方程,基于功率键合图,运用仿真软件AMEsim对液压支架立柱系统建立仿真模型,研究液压支架移架过程的动态特性。对泵站流量、伸缩缸的升降位移、伸缩缸与管路接口、液控单向阀的通流面积、供液管径等工作参数优化匹配,获得提升液压支移架速度的有效途径。To realize fast moving frame based on enough initial-support power is a difficult problem of fully mechanized mining face support. Analysed the working principle of large mining height hydraulic support with double telescoping control system and established the state equation of hydraulic support lifting column process. Based on the power bond graph, we used simulation software AMEsim to build simulation model for the hydraulic support column system and researched the dynamic behavior of hydraulic support moving process. It finished the parameters optimized matching which included pump station flow, lifting displacement telescopic cylinders, telescopic cylinders and pipeline Interface, flow area of hydro-control check valve, area of feed pipe and got effective ways for promoting hydraulic support fast moving.
