摘要 基于计算流体动力学(CFD)方法,利用自有程序结合商业软件处理大跨桥梁风致振动中的流体-固体耦合问题,使用三维桥梁结构模型,进行大跨桥梁风致振动的数值仿真。仿真结果符合实际物理现象,并且所得到的结构气动参数同已有仿真方法的数值结果相比,与风洞试验结果更加接近。这些数值仿真表明,该计算流体动力学方法可以比较准确地进行大跨桥梁的气动特性分析,可以为大跨桥梁建设提供重要的设计基础。 A novel computational fluid dynamic (CFD) method was proposed. Fluid-structure interaction problem was solved by self-developed codes combined with ANSYS software. Three dimensional CFD modelling was used to implement numerical simulation of wind induced vibration for long span bridges. The simulation flow fields are consistent to the actual physical phenomenon, and the computed aerodynamic parameters are much closer to the wind tunnel results than other simulation results. These numerical simulation results propose that the present CFD method can give accurate analysis of aerodynamic characteristics for long span bridges, and this method can be an important basis of the design of long span bridges.
