摘要

采用有限元分析软件ANSYS对500 kV双回路直线型圆管角钢输电塔进行了静动力分析,研究方法及主要结论如下:运用静风极限承载力的分析方法,计算出铁塔在各个方向的极限承载力较为接近,通过塔体动力特性的分析,变刚度处设计应予以重视。
Studying the static and dynamic characteristics of a 500 kV double circuit intermediate tower consisted of steel tubes and angel steels is very necessary.Some conclusions are shown as follows: results show that ultimate load capacity of different parts of the tower is nearly the same,calculated by using finite element software ANSYS,modal analysis shows that designing on the changing slope of the tower should be paid more attention to.
