摘要
考虑平衡钢丝绳和上端激励对摩擦提升系统卡罐时钢丝绳振动的影响,利用Hamilton原理建立变长度提升钢丝绳横向振动动力学模型。应用有限差分法离散化偏微分方程,并以某煤矿副立井塔式多绳摩擦提升系统为例,分析了外界激励频率和阻尼对钢丝绳横向振动的影响。
Considering balance wire rope and the upper end of the incentive to vibration of wire rope for block cage of mine hoisting system. Hamilton principle was used to establish the variable length of steel rope transverse vibration dynamic model for block cage. The finite difference method was used to discretize the partial differential equation to ordinary differential equation. The mine hoisting system was used to the example to analysis the data.
