In order to evaluate the influence of rail corrugation on the fatigue life of bogie frame of high-speed EMU, a vehicle system dynamics model considering rigid-flexible coupling was established considering flexibility of bogie frame. The dynamic stress of the key part of bogie frame was obtained on the measured track irregularities in the presence of rail corrugation. Fatigue life of key parts of bogie frame was predicted according to modal superposition method and nominal stress method. The results show that the rail corrugation will increase the fatigue cumulative damage of the key parts of bogie frame and shorten its overall service life. Structural fatigue damage due to rail corrugation should be taken into consideration when designing bogie frame structure of high-speed EMU. Structural optimization design of key parts of bogie frame should be conducted based on vibration fatigue life prediction.
