| 摘 要： | 以5A-ZM2型500kV输电塔塔-线体系为例，建立了塔-线体系ANSYS三维有限元分析模型。依据谐波合成法生成作用在输电塔塔-线体系上的风速时程，在五种攻角风荷载作用下，对输电塔位移、输电线位移、主材应力分布和塔的基底反力进行了计算分析，讨论了输电线与输电塔动力耦合作用对输电塔的影响，并提出一些有益的结论。

| Abstract: | Using software ANSYS, this paper builds the 3-D finite element model of transmission tower-line system , which is based on the 500kV 5A-ZM2 transmission tower. The time histories of wind speed acting on transmission tower-line system are simulated with the harmony superposition method. The displacements of tower and line, the stress distribution of main member and the foundation reaction are calculated and analyzed for five incidences of wind load. In addition, this paper discusses the effect of the tower-line interaction on the transmission tower and some useful results are derived. |
