With the increment of running mileage, polygonal wear appears in the circumferential direction of the wheel, which will aggravate the impact vibration between the wheel and the rail and affect the running safety and stability of the vehicle. Due to the heavy load and the higher running speed, the effect of wheel polygonal wear on the express freight train cannot be ignored. Besides, the running safety and stability may be further deteriorated when the train runs in the complex environment especially on the bridge and in the crosswind. In this paper, the dynamic model of train-track-bridge are established, and the effects of wheel polygonal wear on the vehicle and track-bridge structure when express freight train runs on the bridge in the crosswind are investigated. The results show that the polygonal wear intensifies the dynamic responses of vehicle and bridge. The amplitude and the order have different effects on the safety and stability of the vehicle.
