摘　　要：液压支架是我国综采工作面的主要技术装备之一,而安全阀的动态特性对支架系统的工作性能影响很大。针对一种新型的大流量安全阀对其动态性能通过建立仿真系统进行研究。利用状态空间法和功率键合图法来建立液压支架用安全阀研究系统的数学模型;利用Matlab编制仿真程序,建立仿真模型以及设计相关实验装置来验证仿真模型的正确性。通过仿真数据分析大流量安全阀动态性能并为下一步优化、设计更大流量安全阀作参考。Hydraulic support is one of the main technical equipment of fully mechanized face in our country, and a large working performance of the frame system of the effect of the dynamic characteristics of safety valve. For a new type of large flow relief valve on its dynamic performance by establishing a simulation system for research. By using the state space method and the power bond graph method to establish the mathematical model of the safety valve used in hydraulic support; Matlab based simulation program, establish the simulation model and design related experiment device to verify the correctness of the simulation model. Finally, through the analysis of the simulation data of high flow safety valve dynamic performance and as a reference for the design optimization, the next step is more large flow safety valve.
