摘要: 介绍了长索结构在风场中的流固耦合振动,总结已有的流固耦合基本理论, 着重介绍弱耦合问题的具体分析过程. 以100 m长索在不同拉索倾角和风向角的多参数流固 耦合风振为例,应用ANSYS-CFX软件分别在层流模型和湍流模型风场中进行数值分 析,得出与力学概念分析基本一致的结果.

Abstract: The fluid-structure interaction (FSI) of the wind-induced vibration of cable structures is studied in this paper. The basic theory of FSI and the analysis procedure of the weak coupling are discussed. An example of the wind-induced vibration in laminar wind model and turbulence wind model of a 100 m long cable with different parameters such as inclined angle and yaw angle is computed with the ANSYS-CFX software. The numerical results agree well with the theoretical analysis.

Key words: long cable structure, fluid-structure interaction, strong coupling, week coupling
