摘　　要：将平衡钢丝绳质量等效在提升容器上,利用Hamilton方程建立塔式多绳摩擦提升系统变长度提升钢丝绳横向振动动力学模型。用修正Galerkin方法将无限维偏微分振动控制方程离散有限维常微分方程。以某矿副立井提升系统运行状态曲线为运动参数输入,仿真分析不同运行阶段提升钢丝绳横向振动规律及刚度、阻尼对横向振动影响。结果表明,在外界干扰激励作用下提升的上行阶段振动更剧烈;增大弹簧刚度、集中阻尼及分布阻尼均可减小钢丝绳横向振幅。As suming the equivalent mass of balance rope with conveyance, a transverse vibration model for mine friction hoist was time-varying length be lumped on the hoisting established in accordance with the Hamilton＇s principle. The modified Galerkin＇s method was used to discretize the partial differential equations. A real mine hoisting system was used as an example to analyse the transverse vibration of wire rope in different operation stages, and the influences of stiffness and damping on the transverse vibration were investigated. The results show that under the excitation of external disturbance, the transverse vibration displacement of hoisting cable is more intense in the ascending stage. The vibration of the rope can be suppressed by modifying the spring stiffness and damping.
