摘要
本文以某电力设计院设计的220KV干字型转角塔为工程背景,利用ANSYS软件建立铁塔的有限元分析模型,并对该塔进行特征屈曲和非线性屈曲分析,得到不同覆冰厚度下塔的位移以及各杆件的受力情况,为转角塔的设计提供参考。
This paper based on the 220kV Type ＂干＂ Angle Tower, designed by some Power Design Institute, for engineering background using ANSYS software to establish the finite element analysis model and carry on the eigenvalue buckling analysis and nonlinear buckling analysis of the tower. We have obtained its display- ment and the forces of all the rods, thus it is better to understand the Mechanics Performance of the Tower, As a reference to the design of comer towers.
