“…investigated the effects of wheel polygonal wear of locomotive on the wheel/rail creep forces and concluded that the anti-slip controller could contribute to the development of wheel polygonal wear (Yang, Xu, Ling, & Zhai, 2022). Moreover, a number of investigations focused on the effects of wheel polygonal wear on dynamic responses of roller bearing of axle box (Liao et al. , 2022; Wang et al.…”

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.

In this paper, a vehicle track coupling dynamic model including bearing outer ring defects is built, the time history of the axle‐box vibration acceleration and the time history of the bearing roller‐outer raceway contact load under the condition of random track irregularity on the Beijing‐Tianjin line are obtained by simulation calculation. The results show that when the outer ring defect of the bearing occurs, the axle box will generate high‐frequency vibration at the resonance peak in the vertical and lateral directions. When the defect on the bearing outer ring is in the small width of 1 mm, the roller only imposes one impact when passing through the defect area. However, when the width exceeds 3 mm, the large defect causes the roller to impose a double impact on the lateral direction of the axle box, due to changes in bearing clearance in the passing‐through process. When the running speed of the train is about 250 km h−1, the width of bearing outer ring defects needs to be limited to within 1 mm, to minimize a series of problems such as structural fatigue caused by the increased bearing roller‐outer raceway contact load caused by bearing outer ring defects.

By grasping the vibration characteristics of the wheelset, the service state of the wheel can be reversely deduced. In this paper, the dynamic model of a rigid–flexible coupling vehicle system, considering wheelset flexibility and axle box flexibility, is established, and a novel resonance excitation loading method for axle box is proposed. Through this method, the vertical force of the wheel‐rail and the resonance response of the axle box vibration under different rigid–flexible combinations of wheelset axle box are obtained. The resonance response characteristics of the axle box of the wheelset and the main factors affecting the resonance characteristics are analyzed. Results show that the bending mode of the wheelset considerably affects the vibration characteristics of the axle box. The mass, the moment of inertia around the x‐axis, and the position of the center of gravity of the axle box also greatly affect the resonance characteristics of the wheel‐to‐axle box.
