摘要
采用Ansys有限元分析软件,建立了输电塔和导线的三维模型,对各种情况下所引起的结构变形作了比较.通过分析发现,输电塔在剧增的裹冰荷载下产生压塌和倾倒破坏.结论表明目前输电塔的设计规范有待改进,以防止超重裹冰情况下产生破坏.
By using Ansys general software,a three dimensional model of transmission towers and wires is taken into account here to compare the deformation of structures under variable conditions.It seems from the analysis that the transmission towers were overwhelmed and collapsed under the increasing ice load.The conclusion indicates that the current design code for transmission towers needs to be upgraded in order to prevent being destroyed under overweight ice load.
