ABSTRACT
With the gradual expansion of the power system scale, the number of transmission lines is also increasing, so a lot of research has been conducted on it. For transmission towers, they are the main supporting structure in transmission lines, and their quality directly affects the safety and economy of the entire transmission line. The transmission tower, as a multi degree of freedom system, has the characteristics of multi-point support, high tower frame, and high tower stability. Among them, the high tower is the most complex and difficult type of design, so it is particularly important to conduct static and steady-state dynamic response analysis on the iron tower. This article took a certain 110 KV branch tower as the research object, and used Abaqus software to analyze the static and dynamic reactions of the structure, which laid the foundation for the next step. At the same time, the correctness of the finite element analysis results in this article was verified through comparison with the specifications. Research has found that iron towers can withstand wind loads and maintain structural stability and safety under normal working conditions. Finite element analysis of tower managers and steady-state dynamic response is practical.
