摘　　要：为实现线控技术在矿井提升机上的应用,以盘式制动器为对象,建立了提升机制动系统模型;考虑弹性变形和摩擦因数影响,进行了刚柔耦合多体动力学仿真及稳定性分析,搭建了基于行星齿轮减速器+螺旋变向的制动系统,得到了制动力和制动间隙消除时间等参数。研究结果表明,该制动执行器在0.078~0.085 s完成对制动盘制动间隙的消除,0.03 s左右制动力趋于17 kN;当静摩擦因数为0.6时,基本无颤振现象,该制动系统具有较好的应用前景。In order to realize the application of wire control technology in mine hoist, taking the disc brake as the object, the braking system model of hoist was established;considering the influence of elastic deformation and friction coefficient, the rigid flexible coupling multi-body dynamics simulation and stability analysis were carried out, and the braking system based on planetary gear reducer + spiral steering was built, and the parameters such as braking force and braking clearance elimination time were obtained. The research results show that the brake actuator can eliminate the brake clearance of the brake disc in 0.078 ~ 0.085s, and the braking force tends to 17 kN in about 0.03s;when the static friction coefficient is 0.6, there is basically no chatter phenomenon, so the braking system has a good application prospect.
