摘　　要：风作用于结构产生的风压力大小取决结构的风压系数。计算风工程(CWE)是利用计算流体力学(CFD)的相关知识,通过流固耦合分析获得复杂结构表面风压切实可行的方法,具有成本低、周期短、效率高的优点。介绍网架辅助设计软件STADS与ICEM和FLUENT的接口程序,将模型自动转入前处理软件ICEM。通过接口程序利用FLUENT软件的流固耦合计算功能获取结构表面风压,并自动计算和读取结构表面的体型系数,为复杂体型的网架结构抗风设计提供计算依据。利用本软件省去了建模的复杂过程,全程采用菜单引导、对话框输入的操作模式,具有简单易行的特点。The wind pressure acting on the structure depends on the coefficient of wind pressure.Fluid-solid coupling analysis is a practical method to obtain the surface wind pressure of complex structure by the computational wind engineering(CWE)based on the knowledge of computational fluid dynamics(CFD),which has the advantages of low cost,short cycle and high efficiency.The interface program between STADS and ICEM,STADS and FLUENT is introduced,which automatically transfers the model to the pre-processing software ICEM.The wind pressure of the structure surface is obtained by using the fluid-solid coupling function of FLUENT through the interface program,and the shape coefficient of the structure surface can be automatically calculated and read.It can provide the calculation basis for the wind-resistant design of grid structure with complex shape.The complicated modeling process will be simplified by using this software,and the whole process adopts the operation mode of menu guidance and dialog box input,which is simple and easy.
