摘　　要：基于有限体积法和非结构网格划分,建立三维输电杆塔风场模型,该模型采用非结构网格对求解区域进行离散,采用Fujita公式和Veno Takeo风场模式模拟气压场和风场,以超高压输电杆塔为例,模拟其动态风场并进行流固耦合动力特性分析,将数值模拟数据与现场实测数据进行对比,说明数据的准确性和所采用方法的有效性。The 3D wind field model of a transmission tower was built based on the unstructured meshes and finite volume method. The model adopted unstructured meshes, which can fit bank better and is used to separate the region. Fujita formula and Veno Takeo formula were used to simulate pressure and wind separately. A transmission tower of Jilin city was modeled to predict its dynamic movement features, the simulation data agree well with the data in field. The analysis shows the accuracy of data and the effectiveness of this method.
