Abstract: This study researched the dynamic characteristics of the TR08 maglev train under strong aerodynamic loads using the sliding grid method. The research investigated the transient aerodynamic load characteristics during open-track single-vehicle operation and meeting scenarios, identified the sources of aerodynamic load oscillation and the train's dynamic characteristics under these loads. Results show that the aerodynamic load of the TR08 maglev train increases with speed, and the pattern is tail train > head train > middle train. The lifting moment is critical for the safe operation of train, and substructure primarily causes load oscillation. The peak value of the pitching moment for a single-segment train shows a hysteresis phenomenon, which is absent in the yawing moment. When single train runs at 600 km/h suspension magnet gap fluctuation exceed safe limits, while when trains meet at 600 km/h instability occurs. This study provides insights into the sources of load oscillation and the train's dynamic characteristics.
