摘    要:客运架空索道系统的固有频率与模态是衡量索道系统固有动力特性的重要指标,固有频率的大小直接关系到结构在各种不同的激励条件下是否会发生动力放大效应与共振。文中首先解决索道系统分析中的有限元建模问题,包括典型柔性索道的模型状态,然后利用ANSYS程序的子空间迭代法求出结构最低各阶的特征值与特征向量,并计算出三种工况下的前40阶固有频率与振动模态,为客运架空索道系统的动力特性分析提供有效的计算方法。

关 键 词:客运架空索道系统 动力特性 固有频率 模态 有限元

Abstract:The natural frequency and modal of passenger aerial ropeway system is the important index of weighing natural dynamic characteristic of the ropeway system, the size of natural frequency is direct relation with whether the dynamic amplification effect and sympathetic vibration of the structure will happen under all kinds of different stimulation. The effective analysis method for dynamic characteristic of passenger aerial ropeway system was developed. The finite element model of the ropeway system, including the model of typical flexible rope, firstly was constructed, then sub space iteration method was proposed to calculate the characteristic value and characteristic vector of the structure, and the results of the former 40 circles of natural frequency and vibration modal under three working conditions were given.
Keywords:Ropeway  Dynamic characteristic  Natural frequency  Modal  Finite element method
