Abstract
Bridge vibration under strong wind load will not only affect the vibration performance of trains on the bridge, but also significantly increase lateral loads on the bridge due to the wind pressure acting on the bridge and trains. Meanwhile, the aerodynamic force and torque of high-speed trains under the strong transverse wind pressure has changed their original vibration characteristics, thus increasing the risk of overturning and derailing. In addition, wind load response on bridges and trains will also be affected by the movement of bridges and trains. The coupling of these factors forms a wind-train-bridge dynamic interaction system.
