摘要

钢丝绳的载荷和变形对悬吊细长结构非常重要。作为细长结构的典型案例,对长挂灯及其挂点布置进行了分析。利用有限元分析软件ANSYS建立了有钢丝绳和无钢丝绳悬挂灯件的有限元模型。通过非线性分析,比较了两种模型的应力和位移计算结果。对比结果表明,有钢丝绳的模型更为合理。悬挂灯的成功安装也说明了该模型的合理性。因此,对于大型细长结构,钢丝绳模型是必要的,它能真实地体现荷载与位移之间的耦合关系。

Analysis of Flexible Lamp with Multiple Hanging Points
The loads and deformations of wire ropes are very important to suspend a slender structure. As a typical case of slender structure, the long hang lamp and its layout of hanging points are analyzed. The finite element models of the hang lamp piece with/without wire ropes are built by ANSYS. After nonlinear analysis, the results of stress and displacement of two models are compared. The comparison results show that the model with wire rope is more reasonable. And the successful installation of the hanging lamp also shows the rationality of this model. Therefore, the wire rope model is necessary for large slender structure, which can embody actually coupling relationship between load and displacement.
