Study on Structure of Drum Type Transmission Tower Based on Modal Analysis

Abstract

Based on the theory of dynamics, this paper takes a certain drum-type transmission tower as the research object, performs parametric modelling based on the actual size, and performs modal analysis on the tower structure through the finite element method. The frequency and mode of the first 20 steps of the transmission tower were extracted. The results of modal analysis show the dynamic characteristics and structural characteristics of the drum-type transmission tower, providing a theoretical basis and foundation for studying the earthquake resistance, wind resistance and other environmental incentives of the transmission tower structure.
