Simulation Study on Wind-Induced Response of Transmission Lines Under Hilly Terrain Conditions
摘要
In order to obtain the dynamic response of wind-induced vibration of transmission lines under various hilly terrain conditions, numerical simulation is carried out in this paper. By studying the influence of wind field characteristics of canyons and channels on the fluid-solid coupling wind-induced vibration of transmission lines, the distribution of aerodynamic coefficients and vertical displacement under different landforms is studied. The ANSYS two-way fluid-solid coupling numerical simulation method is used to simulate the transmission lines in canyons and pass landforms under different working conditions, and the dynamic wind-induced response of transmission lines under different terrain boundaries is calculated.
