Finite Element Simulation Calculation of Vibration Mode of Transmission Line Guide Ground and Elastic Boundary of Iron Tower

As an important part of the transmission line, the safe and reliable operation of the guide wire is the basis for the smooth operation of the whole transmission system. However, with the gradual expansion of the transmission network, the guide wire accidents occur frequently due to wind weather, which has attracted widespread attention. In this paper, the modal analysis is carried out under the condition of fixed clamping at both ends through finite element modeling, and the vibration mode and natural frequency of the guide wire are analyzed, which lays a solid foundation for the wind vibration prevention and control of the guide wire. In addition, on the basis of the finite element model, the iron tower model is added to construct the coupling system between the iron tower and the guide wire, and the modal analysis is carried out to analyze the vibration modes and vibration natural frequencies under the system, which provides a strong theoretical support for the design of the iron tower, the characteristics of the guide wire and the dancing calculation.
