Research on Mine Hoisting System of the High-speed Rotary Dynamic Modeling and Vibration Control Method

针对矿井高速回转提升系统由于设计制造安装等方面的缺陷以及外界干扰的影响,导致提升系统运行时钢丝绳产生摆动问题。以矿井高速回转提升系统中柔性钢丝绳的摆动控制为研究对象,通过动力学模型计算和虚拟样机法数值仿真分析,对提升系统在运行过程中钢丝绳摆动量的影响因素进行了深入研究。研究结果表明,减小提升系统钢丝绳摆动量可以采用减小基座底板小孔与卷丝轮之间的距离、基座底板小孔直径以及采用弹性模量较小的钢丝绳方法降低提升系统运行时钢丝绳的摆动量。

In view of the main hoisting system in high-speed rotary,the defect of design and manufacture and influence of outside interference result in inevitable vibration of wire rope. The flexible steel wire rope in mine hoisting system of the high-speed rotary control as the research object,by establishing the dynamic model,this paper adopts the analytical method and the virtual prototype method to analyze the dynamic model system,and studies the influencing factors in the running process. Results show that wire rope hoisting system of the pendulum momentum can decrease the distance between the plate holes and thread rolling wheels. Base bottom hole diameter and the smaller elastic modulus can effectively reduce the wire rope momentum with wire rope hoisting system runtime.
