摘要
天轮轴向摆动会对缠绕式提升系统的钢丝绳产生横向振动的影响,通过应用Hamilton原理,建立缠绕式提升钢丝绳横向偏微分振动方程。利用有限差分方法,将横向激励作用下提升钢丝绳偏微分振动控制方程进行离散化求解,得到提升钢丝绳横向振动特性。仿真分析了缠绕式提升系统在上升过程中,天轮轴向摆动对矿井提升系统提升钢丝绳横向振动影响,为深入研究缠绕式提升系统钢丝绳横向振动提供了途径与方法。
Based on the influence of the axial swing of the Skywheel on the transverse vibration from wire rope in the winding hoisting system. The transverse partial differential vibration equation of winding hoisting wire rope has been established by Hamilton principle. By using the finite difference method, the partial differential vibration control equation of hoisting wire rope under transverse excitation has been discretized, and the transverse vibration characteristics of hoisting wire rope have been obtained. The influence of the axial swing of the Skywheel on the lateral vibration of the hoisting wire rope in the winding hoisting system has been simulated and analyzed, which provides a way and method for further study of the lateral vibration of the wire rope in the winding hoisting system.
