输电铁塔的静力学分析

A Study on the Static Analysis of the Transmission Tower

在大型有限元软件ANSYS中,建立220 kV直线猫头塔的有限元模型,以最大风载和最大覆冰两种工况为边界条件施加荷载,对铁塔进行静力学分析,得到铁塔在两种工况下的位移情况和最大应力值。研究结果可为铁塔的动力学分析等后续研究提供理论基础,并对日常运检工作有一定的指导意义。

This paper introduces the establishment of the finite element model of the 220 kV straight-line cat-head type tower by means of the ANSYS. Loads can be applied based on the boundary condition including two working conditions with maximum wind load and icing. Displacement situations and maximum stress values in the two working conditions can be obtained through the static analysis of the tower. The results of the research can provide theoretical basis for follow-up researches such as the kinetic analysis of the tower as well as giving guidance for the work of daily operation and maintenance.
