本文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建立了液压系统的数据模型,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 principle of the hydraulic system during the monorail crane braking. It is concluded that the spring stiffness and the throttle flow area are the main factors affecting the braking system. The data model of the hydraulic system was established by MSC.EASY5. The unloading time of the hydraulic cylinder under the spring force was simulated. The results show that the response time of the braking system meets the requirements of coal safety regulations; Flow area, will have an impact on the braking system.
