摘要:
为研究上海市区独立平台电缆终端杆风振响应，基于有限元法，建立了独立平台电缆终端杆的风振分析模型，采用双向流固耦合的方法，分析了不同风向（0°和90°）和风速（5，10，15，20，25和30m/s）条件下电缆终端杆的风振响应及电缆终端杆附近的瞬态流场形态。研究结果表明：电缆终端杆在0°风向条件下的位移大于90°风向条件下，顺风向抖振在风振中占据主导地位，在5m/s风速条件下，电缆终端杆的位移符合规范要求，但是在30m/s基本风速条件下，电缆终端杆左杆的位移超过了规范限值。电缆终端杆的风振由低阶和高阶振型共同控制，随着风速的增大，低阶振型在风振中的贡献提高，高阶振型在风振中的贡献下降。
Abstract:
To investigate the wind-induced vibration response of cable terminal pole on an independent platform in the urban area of Shanghai, a wind vibration analysis model was established based on finite element method. A bidirectional fluid-structure interaction (FSI) approach was adopted to analyze the wind-induced response of the terminal pole and the transient flow characteristics around it under different wind directions (0°and 90°) and wind speeds (5, 10, 15, 20, 25, and 30 m/s). The results show that the displacement of the cable terminal pole under the 0°wind direction is greater than that under the 90°wind direction, and the along-wind buffeting dominates the wind-induced vibration. At a wind speed of 5 m/s, the displacement of the cable terminal pole meets the design code requirements, while at the basic wind speed of 30 m/s, the displacement of the left pole exceeds the specification limit. The wind-induced vibration of the cable terminal pole is governed by both low-order and high-order modes. As the wind speed increases, the contribution of the low-order modes becomes more significant, while that of the high-order modes decreases.
