Research on Emergency Braking Simulation of Shaft Hoisting System

摘要

摘要: 为了研究竖井提升系统在不同参数下紧急制动特性规律，采用ANSYS、SolidWorks和RecurDyn软件建立了矿井提升机多柔体动力学仿真模型；运用控制变量法分析了制动力矩和罐笼悬垂高度对提升系统紧急制动特性的影响。结果表明，对提升机实施紧急制动时，钢丝绳张力和罐笼振动都有较大的波动，钢丝绳张力平均值、最大幅值以及罐笼减速度平均值和最大幅值都随制动力矩的增大而增大；罐笼悬垂高度越大，提升系统刚度和阻尼越小，制动安全性降低。

Abstract: In order to study the characteristics of the emergency braking of shaft hoisting system under different parameters, we use ANSYS, SolidWorks and RecurDyn software to establish MFBD（multi-flexible body dynamics）model of mine hoist, and use the method of control variable to analyze the effect of braking torque and distance of cage. The results show that when emergency braking is applied to the hoist, wire rope tension and cage vibration have big fluctuation, the average and maximum amplitude of wire rope tension and the average and maximum amplitude of cage deceleration increase with the increasing of braking torque; the higher the hanging height of the cage, the smaller the stiffness and damping of the system, and the braking safety is lower.
