考虑流固耦合效应的风荷载数值仿真计算

摘要

使用 ANSYS 软件，通过改变影响结构流固耦合效应的风速和风向角等主要外界因素，对风荷载下的低层建筑结构进行不同湍流模型的数值模拟，输出计算结果，并与实测数据进行比较，得到风速和风向角对其结构的风致振动特性和流固耦合效应的具体影响规律。%In this paper,the software of ANSYS is used to analyze the fluid-structure interaction. It changes the main external factors effecting fluid-structure interaction in wind-induced vibration of wind speed and direction angles. Then it has the numerical simulation of the low-rise building structure under the wind load and outputs the calculation result. The result of wind-induced vibration characteristics and the rules of in-fluence of fluid-structure interaction with wind speed and wind angles are summarized by the comparison with real measured data.
