Considering the expansion of high-speed rail networks and the escalation of high-speed train (HST) velocities has elevated the significance of aerodynamic interactions between HSTs and bridges. Therefore, we developed a new moving train & infrastructure rig to evaluate the aerodynamic performance of trains and infrastructures (e.g., bridges), thus determining the system’s stability and safety. In the present work, a novel experimental method enables the model, scaled between 1:8 and 1:30, to reach a maximum velocity of 50m/s, effectively emulating real-world operational conditions. By integrating with the controlled environment, aerodynamic tests on trains can be conducted in a wind environment, particularly focusing on the behavior of high-speed trains under crosswinds.
