Abstract

Transmission tower is an important equipment for overhead transmission and distribution lines, and its structural strength directly affects the safety of transmission lines. ABAQUS software was used to establish the finite element model of 66kV drum-type tower, and the calculation methods of gravity load and wind load were presented. The stress distribution and displacement of 66kV drum-type tower under gravity load only and under the combined action of gravity load and wind load are obtained. The results show that the maximum stress of the drum-type tower under combined action of gravity load and wind load is much larger than that under gravity load only. The maximum stress points under combined action of gravity load and wind load are the windward surface at the connection between the cross-arm and the main material and the windward surface at the main material of the tower legs, whereas the maximum stress point under gravity load only is located in the vicinity of the cross-arm of the drum-type tower.
