Characteristics, Mechanisms, Influences and Counter Measures of High Speed Wheel/Rail Wear: Transverse Wear of Wheel Tread

Study on Influence of Diversified Parameters of Vehicle and Track on Wheel Hollow Wear

“…As could be seen from Figures 5-10, (1) whether the base value or sensitive value is taken for damping of antihunting motion dampers, longitudinal stiffness of tumbler journal box node, lateral stiffness of air-spring suspension, vertical damping of secondary suspension, vertical stiffness of track, and vertical damping of track, the cumulative wear power dissipation is unevenly distributed in the lateral direction of the wheel tread. It is indicated that the wheel hollow wear is unavoidable in the presence of wheel and rail tread, which is consistent with the field observations [1,18]. From the peak features in Figures 6-11, there is a significant peak at the position of lateral coordinate of -10 mm of the wheel tread, which is basically the same as the position of the maximum point of the hollow wear measured on the filed [2,3].…”

“…Jin Xuesong et al carried out the detailed analysis and summary of the transverse wear of high-speed wheel/rail of China (the hollow wear on wheel tread and the wheel flange wear), including its characteristics, the formation mechanism, its effect on high-speed train dynamic behavior, and the measures against such wear pattern. When the hollow wear is in a certain depth range, wheel set hunting occurs and the comfort of vehicle drops [18]. The paper proposed seven measures to suppress or slow down the hollow wear of wheel.…”

“…Wheel hollow wear is an inevitable trend in the wheel-rail wear [18], but how to better characterize the hollow wear and how to slow down the hollow wear are an urgent problem to be solved. Karttunen proposed a multiparameter quantitative characterization method for the hollow wear wheel, analyzed the relationship between these parameters and wheel wear and fatigue, and proved the validity of these parameters in describing the hollow wear wheel [25].…”

“…Therefore, it is necessary to study the mechanism of wheel hollow wear from the view of multiparameter and cumulative wear of the wheelrail system. At the same time, it is necessary to study the effect of vehicle suspension parameters on the hollow wear of the wheel in both the optimization of the wheel/rail profile matching and the antijamming performance design of the vehicle structure in suppressing the hollow wear of wheel [18]. Suspension characteristics can play a significant role in rolling contact fatigue (RCF) and wear, corrugation, and noise [27].…”

Wear Problems of High-Speed Wheel/Rail Systems: Observations, Causes, and Countermeasures in China

“…To characterize the dynamic behavior of high-speed EMUs, a depth limit of 0.2 mm was once recommended for hollow wear based on test results and detailed simulation analyses, and found to be effective [59,60]. Recently, Cui et al [61] proposed a dynamics approach to determine the threshold depth for wheel reprofiling with hollow wear, in which the side-wear (asymmetric wear on the two wheels of a wheelset) was also considered and the running stability, riding quality, and curving stability were all evaluated.…”
