“…Dong et al. reported the failure of the wire bracket installed on the axle box through the field test and numerical simulation and concluded that the crack initiated from the weld defect and the combined impacts due to wheel polygonal wear and rail corrugation serve as the main driving force for fatigue failure (Dong, Wang, Dai, & Li, 2023).…”

“…Besides, the high-level vibration arising from the wheel polygonal wear can also give rise to the non-linear vibration in the axle box front cover of high-speed train and further contribute to the failure of connecting bolts (Feng, Qu, Li, Dai, & Shu, 2023). Dong et al reported the failure of the wire bracket installed on the axle box through the field test and numerical simulation and concluded that the crack initiated from the weld defect and the combined impacts due to wheel polygonal wear and rail corrugation serve as the main driving force for fatigue failure (Dong, Wang, Dai, & Li, 2023). high frequency impacts excite the natural frequency of lifeguard thereby reducing fatigue lifetime (Li et al, 2019).…”

PurposeThis review aims to give a critical view of the wheel/rail high frequency vibration-induced vibration fatigue in railway bogie.Design/methodology/approachVibration fatigue of railway bogie arising from the wheel/rail high frequency vibration has become the main concern of railway operators. Previous reviews usually focused on the formation mechanism of wheel/rail high frequency vibration. This paper thus gives a critical review of the vibration fatigue of railway bogie owing to the short-pitch irregularities-induced high frequency vibration, including a brief introduction of short-pitch irregularities, associated high frequency vibration in railway bogie, typical vibration fatigue failure cases of railway bogie and methodologies used for the assessment of vibration fatigue and research gaps.FindingsThe results showed that the resulting excitation frequencies of short-pitch irregularity vary substantially due to different track types and formation mechanisms. The axle box-mounted components are much more vulnerable to vibration fatigue compared with other components. The wheel polygonal wear and rail corrugation-induced high frequency vibration is the main driving force of fatigue failure, and the fatigue crack usually initiates from the defect of the weld seam. Vibration spectrum for attachments of railway bogie defined in the standard underestimates the vibration level arising from the short-pitch irregularities. The current investigations on vibration fatigue mainly focus on the methods to improve the accuracy of fatigue damage assessment, and a systematical design method for vibration fatigue remains a huge gap to improve the survival probability when the rail vehicle is subjected to vibration fatigue.Originality/valueThe research can facilitate the development of a new methodology to improve the fatigue life of railway vehicles when subjected to wheel/rail high frequency vibration.
