摘　　要：工业的发展对电力的需求越来越多,输送线路的环境也越来越复杂,而铁塔是支持导线及避雷线的钢结构。针对三种腹杆布置形式不同的塔架结构,利用软件,建立有限元计算模型,进行有限元的计算,通过模态分析和屈曲分析得出支撑布置形式对结构自振特性的影响以及支撑布置方式对结构用钢量和承载力的影响,找出最优的支撑布置方案,为生产提供依据。The development of industry demand more and more powers ,and the environment of conveyor line become more complicated the steel power as the steel structure to support lead wire and ground wire. In this paper, for tower structure of arrangement of three different support. Calculation of finite element analysis using. Choose the best layout program by the means of mode analysis and buckling analysis, providing the basis forproduction.

关 键 词：支撑 塔架结构 模态分析 屈曲分析
