摘　　要：针对因掘进机液压系统中平衡阀密封件频繁受损,制约工作面掘进效率的问题,基于对掘进机结构组成及负载敏感系统研究的基础上,利用AMESim软件搭建截割部升降液压回路仿真模型,并对中位等待、截割上升、截割部下降工况下油缸的压力变化情况进行仿真,为优化液压回路奠定了基础。Based on the research on the structure of the driving machine and the load—sensitive system,based on the AMESIM software,the simulation model of the pressure change of the cylinder under the condition of median waiting,cutting up and cutting down is built.

关 键 词：液压回路 平衡溢流阀 失效
