摘要:
独立平台电缆终端杆在强风作用下经常发生破坏,为了优化电缆终端杆几何参数,采用ABAQUS的CFD模块建立了电缆终端杆和流场的数值分析模型,基于双向流固耦合的方法研究了基本风速(30m/s)条件下平均壁厚(9.88mm、11.88mm、13.88mm和15.88mm)、杆高(33m、30m和27m)和锥度(0、1/200和1/100)对电缆终端杆的风振响应的影响。研究结果表明:增加电缆终端杆壁厚、降低主杆高度、增加主杆锥度均能有效抑制强风作用下电缆终端杆的风致振动;不同几何参数条件下电缆终端杆的风振均由低阶振型(第一或第二阶振型)控制;在风向为0°时,高阶振型的贡献随着平均壁厚的增大,杆高的降低和锥度的增大而增大,在风向为90°时,高阶振型的贡献随着平均壁厚的增大,杆高的降低而减小,随锥度的增大变化不明显。
Abstract:
Independent platform cable terminal poles are often subjected to structural damage under strong wind loads. To optimize geometric parameters of cable terminal poles,a numerical model of the cable terminal pole and surrounding flow field was established by using the CFD module in ABAQUS. Based on a two-way fluid-structure in?teraction(FSI)approach,the wind-induced vibration response of the terminal pole was investigated under a basic wind speed of 30 m/s, considering variations in average wall thickness(9.88 mm, 11.88 mm, 13.88 mm, and 15.88 mm),pole height(33 m,30 m,and 27 m),and taper ratio(0,1/200,and 1/100). The results indicate that increasing the wall thickness,reducing the height of the main pole,and enlarging the taper ratio of the main pole can effectively suppress wind-induced vibrations of the cable terminal pole under strong winds. The wind-in?duced vibration of cable terminal poles under geometric parameters is primarily governed by low-order modes(the first and second modes). When the wind direction is 0°,the contribution of higher-order modes increases with larg?er average wall thickness, lower pole height, and greater taper ratio. However, under 90° wind direction, the contribution of higher-order modes decreases with the increase of average wall thickness, the decrease of pole height,while showing little variation with taper ratio.
