Fatigue damage prediction of metro bogie frame based on measured loads
International Journal of Fatigue（2022）
摘要
•The completeness of the measured loads was verified.•Bogie loads were classified into quasi-static and dynamic regions.•Bogie modal vibration and rail corrugation were studied to adjust the bogie loads.•The new loads were applied to predict another frame running on a different line.
