Abstract: A system for testing aerodynamic characteristics of a high-speed moving vehicle-bridge system and subsidiary facilities thereof under a crosswind includes a vehicle model, a starting mechanism, a buffer mechanism, a wind tunnel test section and guide rails. The guide rails pass through the wind tunnel test section; the starting mechanism and the buffer mechanism are separately located at both ends of the guide rails. The guide rails include an acceleration section and a deceleration section. The starting mechanism is located in the acceleration section, and the buffer mechanism is located in the deceleration section; the vehicle model starts to run at the starting mechanism and stops at the buffer mechanism; an instantaneous speed of the vehicle model in the acceleration section is not less than 100 km/h. The present invention carries out simulation tests on various infrastructures, their subsidiary facilities and trains through scale models.
