摘　　要：主要介绍了单轨吊机车在紧急制动过程中液压系统的工作原理,并使用AMESim软件对液压系统进行仿真分析,结果表明,滚轮换向阀的开启过程对液压缸卸油速度影响很小,而其通径的大小对液压缸卸油速度的影响较大。为保证紧急制动的可靠性,以及满足煤矿安全规程对制动系统响应时间的要求,需要更换较大通径的滚轮换向阀。This paper mainly introduces the working principle of monorail emergency braking hydraulic system, and we use the AMESim to model the hydraulic system, the result shows that, the process of opening roller reversing valve has a little effect on the speed of unloading oil, but the diameter has great influence.In order to ensure the reliability of emergency braking system, and meet the requirement of the coal mine safety regulation on the response time of a braking system, we need roller reversing valves with larger diameter.
