基于ANSYS输电铁塔覆冰屈曲分析

Buckling Analysis of Transmission Tower Icing Based on ANSYS

应用ANSYS有限元分析软件,对已在运行的输电铁塔覆冰进行屈曲有限元分析,得出详细的计算结果。通过应用ANSYS对某线路铁塔在覆冰与风载共同载荷下的稳定性、覆冰增加、不均匀覆冰引起的不平衡张力及风载进行分析。研究表明:过载、风载及不均匀覆冰是倒塔的主要原因。

The ANSYS software is used to analyze the buckling finite element of the icing of transmission tower in operation,and calculation results in detail were obtained. By the application of ANSYS,the stability under icing and win load,the unbalanced tension caused by increasing icing, the asymmetrical icing distribution and the wind load of a certain transmission tower were analyzed. Study results show that the overload, the wind load and the asymmetrical icing distribution are main reasons of tower collapse accidents.
