摘　　要：介绍了某型硬岩掘进机截割升降液压回路的工作原理,利用AMESim软件建立了该系统的仿真模型,通过模型仿真和试验分析,得到了截割升降油缸无杆腔内液压冲击是平衡溢流阀组密封损坏的根本原因,并提出了密封损坏的解决方案。The working principles of cutting lift hydraulic circuit in a specific type of hard rock roadheader were introduced. The system simulation model was established by using AMESim software. The results of the simulation and experiment shows that balance relief valve seal damage was due to hydraulic impact in cutting cylinder＇s big cavity. Finally,the solutions were proposed to avoid seal damage.
