以2JTP-1.2型矿井提升机为研究对象,应用Pro-E软件建立了提升机制动器和离合器的三维模型,应用ADAMS软件建立了液压系统模型。将液压系统与机械系统模型进行耦合,建立了矿井提升机制动系统虚拟样机。对提升机制动系统运动学和动力学进行了仿真,对提升机制动系统中的闸瓦摩擦参数以及液压系统一级制动油压对制动性能的影响进行了研究。指出闸瓦摩擦参数以及液压系统一级制动油压对制动性能的影响都很显著,因此对于闸瓦摩擦系数及一级制动油压应当在优化分析的基础上进行合理选择。
Taking the 2JTP-1.2 mine hoist as the research object, a three-dimensional model of the hoist brakes and clutches was established by Pro-E software. The hydraulic system model was established by ADAMS software. The hydraulic system and the mechanical system model are coupled to establish the mine hoist brake system virtual prototype. The kinematics and dynamics of the brake system of the hoist are simulated. The influence of brake friction parameters on the brake system of the hoist and the braking performance of the first-stage brake hydraulic system are studied. It is pointed out that the friction coefficient of brake shoe and the first-stage brake hydraulic pressure of hydraulic system have significant influence on the braking performance. Therefore, the friction coefficient of brake shoe and the first-stage brake hydraulic pressure should be rationally selected on the basis of optimization analysis.
