［摘要］采用谐波合成法(WAWS)生成脉动风速时程，并根据输电铁塔结构的空间结构特点生成输电铁塔的脉动风振荷载，利用有限元软件PowerTower和ANSYS进行输电铁塔结构的强风仿真分析，研究了不同风速、风向和阻尼比情况下输电铁塔结构的风振响应。研究结果表明，随着风速的提高，输电铁塔的位移和轴力响应不断变大，风速的大小、风向对输电铁塔结构的响应影响很大，阻尼比对输电铁塔结构的响应影响较小。

Abstract:The weighted amplitude wave superposition method（WAWS）was used to simulate wind speed time series, and the pulsating wind vibration load was generated according to the characteristic of the spatial structure of the transmission tower. The finite element programs Power Touer and ANSYS were used to conduct strong wind simulation analysis of transmission tower structure. The wind-induced vibration responses of the transmission tower under different wind speed, wind direction and damping ratio were studied. The results show that with the increase of wind speed, the displacement and axial force response of the transmission tower become larger and larger. The wind speed and wind direction greatly influence the response of the transmission tower structure. The influence of damping ratio on the response of the transmission tower structure is small.

Keywords:transmission tower; strong wind; WAWS; simulation analysis
