| 摘 要： | 以提升系统中变长度柔性钢丝绳的纵向振动为研究对象，考虑钢丝绳刚性运动与变形运动的相互影响，应用Hamliton原理建立变长度提升系统钢丝绳运动微分方程，同时，利用五次多项式拟合得到的电梯理想运行状态曲线作为运动参数输入，对所建模型进行了算例分析。数值仿真结果表明：本文的方法能较好地反映变长度提升系统钢丝绳的纵向振动特性，推导出的方程为电梯钢丝绳纵向振动特性的进一步分析提供了依据。

| Abstract: | Aimed at the longitudinal vibration of rope hoisting systems with time-varying length, the governing equations are developed employing energy method and the Lagrange method considering mutual influence of the rigid motion and deformation of rope. In the mean time, The motions of elevator hoisting systems were illustrated to evaluate the proposed mathematical models. The results of simulation show that the modeling methods can represent the longitudinal vibration of rope hoisting systems with time-varying length in the paper. The governing equations derived can provide reference for further study. |
