Effect of wheel initial state on the growth of polygonal wear on high-speed trains

“…, 2019; Wu, Shang, Pan, Zhang, Shi, & Xiao, 2022; Wu, Xie, Liu, Wu, Wen, & Mo, 2022) and traction-induced wheelset torsional vibration and associated self-excited stick slip vibration (Spangenberg, 2020), as shown in Figure 2. In addition, the initial irregularities on the wheel circumference (Cai, Chi, Wu, Yang, & Huang, 2023; Ye, Shi, Krause, Tian, & Hect, 2020; Kang et al. , 2022), wheelset flexibility (Peng, Iwnicki, Shackleton, Crosbee, & Zhao, 2019; Peng, Han, Chu, Gao, Liu, & Xiao, 2019) and traction (Chen et al.…”

“…The proposed formation mechanism of wheel polygonal wear includes the bending of wheelset (Jin, Wu, Fang, Zhong, & Ling, 2012;Tao, Xie et al, 2020), P2 resonance of wheel/rail (Tao, Wen, Liang, Ren, & Jin, 2019;Cai, Chi, Tao, Wu, & Wen, 2019), rail localized bending between two wheelsets in a bogie (Wu, Rakheja, Cai, Chi, Ahmed, & Qu, 2019;Wu, Wu, Li, Shi, & Xu, 2019;Cai, Wu, Chi, Yang, & Huang, 2022;Qu, Zhu, Zeng, Dai, & Wu, 2020;Ma, Gao, Cui, & Xin, 2021), the structural resonance of bogie frame (Wu, Du, Zhang, Wen, & Jin, 2017), as well as the frictional self-excited vibration of wheelset-track system (Zhao et al, 2019;Wu, Shang, Pan, Zhang, Shi, & Xiao, 2022;Wu, Xie, Liu, Wu, Wen, & Mo, 2022) and traction-induced wheelset torsional vibration and associated self-excited stick slip vibration (Spangenberg, 2020), as shown in Figure 2. In addition, the initial irregularities on the wheel circumference (Cai, Chi, Wu, Yang, & Huang, 2023;Ye, Shi, Krause, Tian, & Hect, 2020;Kang It can be seen that the formation mechanisms of wheel polygonal wear are mainly attributed to the resonance of the natural vibration mode of the system, especially for the modes that affect the wheel/rail interaction. These suggest that the wheel polygonalization is a general wear process for rail vehicles, and a perfect round wheel could also tend to be an OOR wheel if the mitigation is not considered in the operation.…”

“…Wu et al reported the evolution of wheel polygonal wear for a high-speed train operating at 300 km/h and pointed out that the maximum vertical acceleration of the axle box can reach up to 400 g due to severe wheel polygonal wear, and the associated impact can excite some high frequency vibration mode (up to around 1,000 Hz) near the double passing frequency of wheel polygonal wear (Wu, Rakheja, & Wu, 2018;Wu, Rakheja, & Qu, 2018). Moreover, the wheel polygonal wear-induced high frequency vibration is obviously greater than those defined in IEC 61373 (Wu et al, 2023), especially for the dominating frequency band of wheel polygonalization (550-650 Hz), as shown in Figure 5. This suggests that the axle box vibration level given in IEC 61373 could underestimate the vibration level of the axle box in the presence of wheel polygonalization.…”

“…However, in the operation, the vibration of axle box is predominated by multiple frequency bands rather than a single frequency band alone (Cai et al, 2021;Wu et al, 2017;Wu, Shang et al, 2022;Wu, Xie et al, 2022). Through analysing field test measurements obtained from nine high-speed railway lines, Wu et al pointed out that the ASD spectrum in IEC61373 mainly focuses on the low frequency range of 20-100 Hz (Wu et al, 2023). This can represent the overall vibration level of 20-100 Hz, whereas still underestimates the vibration level near the frequency of wheel/rail coupled mode (P2 force).…”

“…The dominating frequency bands, including P2 force and other dominating frequencies contributing to the formation of rail corrugation and wheel polygonal wear, should be treated carefully in the modal matching. Wu et al summarized the typical wheel/rail coupled vibration modes of rail vehicles in the vertical direction (Wu et al, 2023), whereas the coupled vibration modes in the lateral direction are still needed to be further clarified. The axle box vibration spectrum could be taken as a representative of wheel/rail coupled vibration, and a database for characteristic vibration spectrums of axle box is thus suggested on the basis of field test measurements.…”
