摘要
主要分析了单轨吊制动过程中液压系统的原理,得出弹簧刚度与节流阀通流面积是影响制动系统的主要因素。并使用MSC.EASY5对液压系统建模,对液压缸在弹簧力作用下的卸荷时间进行了仿真,结果表明,制动系统的响应时间满足煤炭安全规程要求;调节节流阀的通流面积,会对制动系统产生影响。
This paper mainly analyzes the hydraulic system principle during the monorail braking, and come to a conclusion that the spring stiffness and the throttle valve flow area are main factors affect the brake system. Then we use the MSC.EASY5 to modeling the hydraulic system, and simulate the unloading time of hydraulic cylinder under the spring force, the result shows that, the response time of a braking system can meet the requirement of the coal mine safety regulation, and change the flow area of throttle valve will affect the brake system.
