摘要：Shape and size of vehicle model in numerical wind tunnel model have a great influence on aerodynamic coefficients of vehicle. A bus running on the steel box girder bridge was used to establish numerical wind tunnel model to study the influence of the parameters of vehicle model on the aerodynamic force coefficients of vehicle and bridge. In the numerical wind tunnel model, respectively established with and without of wheels and different height of the vehicle model to study the aerodynamic characteristics of vehicle and bridge. The results show that, with and without wheels in the established numerical wind tunnel model has a great influence on the aerodynamic force coefficient of vehicle. The height variation of vehicle chassis plays an important role only for separate aerodynamic force coefficients of vehicle and bridge.
