摘　　要：介绍一种高端液压支架用大流量安全阀的工作回路与结构特点,根据其特点设计了大流量安全阀的试验方案,利用Simulink对其动态特性进行仿真分析。通过仿真分析可知,增加弹簧的刚度可以优化动态特性。研究内容为分析该阀的结构参数变化及其性能指标提供了理论依据。The work loops and body features of a high flow safely valve in a advanced hydraulic support were introduced and a tes- ting program for the high flow relief valve was designed according to its characteristics. Simulink was used to make dynamic characteris- tic simulation. Through simulation analysis, it is concluded that increasing the spring stiffness can optimize its dynamic characteristics. The research provides a theoretical basis for analyzing the structural parameters changes and performance indicators of the valve.
