“…Conducting a large number of experiments, Jin et al 6 hypothesized that the polygonal wear of the wheel was caused by the first order bending vibration of the wheelset. Through the track mode calculation theory, Dai et al 7 discovered that the resonance with the third-order mode of the track is the main reason for the formation of the 20th order wheel polygon, and they validated the theory with experiments. Yang et al 8 used field tests and numerical simulation to investigate the formation mechanism and key influencing factors of wheel high-order polygonization, and discovered that P2 resonance is the primary cause of wheel polygonization, and that first-order bending vibration of the wheelset aggravates the wear.…”

Wheel polygon wear has emerged as a critical issue in the development of high-speed trains in China, but the mechanism underlying its formation remains unknown. The formation mechanism and its effect factors of wheel polygonalization are investigated in depth in this paper using theoretical analysis and numerical simulation. A longitudinal self-excited vibration and vertical modal vibration coupling model of wheel-rail is established, considering the comprehensive effects of wheelset flexibility, vehicle spring mass, and foundation under rail. The critical condition of the system Hopf bifurcation is determined by theoretical analysis, and the longitudinal vibration characteristics of the wheel are studied using numerical simulation. Furthermore, the influence factors on wheel polygonalization are investigated. The research method makes a useful attempt to unify the relevant viewpoints of resonance theory and self-excited vibration theory, and the research results have theoretical guiding significance and engineering reference value for the prediction and suppression of wheel polygonal wear.

“…It was found that the first-order symmetric vertical bending mode and the first-order antisymmetric vertical bending mode excitation of the wheel pair caused the largest amount of transverse slip of the wheel, which had a greater influence on the generation and further evolution of the wheel polygon. Dai et al [5,6] applied the theory of cut mark formation in metal cutting to analyze and study the polygonal wear of wheels in highspeed railways, and innovatively proposed that the polygonal wear mechanism of wheels in high-speed trains based on the cutting principle and the third-order modal vibration of the steel rail between the wheels of the bogie are the main reasons leading to the high-order polygonal wear of wheels in high-speed trains. In terms of dynamic performance, Han et al [7] investigated the effect of wheel polygon on the vibration and noise of high-speed vehicle system, and found that the noise in the vehicle will increase significantly with the increase of the wave depth of the wheel polygon; Wang et al [8,9] established a rigid-flexible coupled dynamics model considering the elastic vibration of the vehicle body, frame, and the wheelset, and investigated the effect of several typical wheel polygons on the dynamic performance of the vehicle system.…”

After the wheels of rail vehicles have been running for a long time, the polygon effect often causes a series of changes in the dynamic response of the vehicle-rail system, and the vibration response of the vehicle and the track also becomes more intense. This will cause the degradation of the vehicle dynamics performance, and cause intense noise of the wheels and the track, which in turn affects the comfort of the ride and the stability of driving. In order to study the impact of wheel polygon on the dynamic performance of high-speed trains, based on the theory of vehicle system dynamics, this paper takes the CRH3 rolling stock as a prototype, and studies its vehicle dynamic performance under the condition of wheel polygon wear. Firstly, a vehicle-rail coupled dynamics model considering rail, wheelset and axle-box flexibility is established to study and analyze the vehicle dynamics performance under wheel polygonal wear, which mainly includes vehicle stability, ride comfort, axle-box vibration acceleration, wheel-rail force and axle dynamic stress. It can be seen through the analysis that low-order wheel polygonal abrasion has a small impact on the stability and ride smoothness of the vehicle; high-order wheel polygonal abrasion has a high excitation frequency of the wheelset, and its transverse component makes the vehicle dynamics deteriorate slightly at high speeds. The high-frequency wheel-rail vertical force due to wheel polygonal wear causes large axle-box vibration acceleration and axle stress fluctuation.

“…The P2 resonance influences the formation of wheel OOR, especially when the track supporting stiffness is large. The wheel tread is cut by the rail surface which is described as the regeneration flutter mechanism (Dai et al, 2019). Then the wheel OOR could rapidly develop and aggravate the resonance vibration and even lead to fatigue failure problems.…”

To examine the effects of rail weld irregularity on the dynamic stress of the bogie frame, a numerical model which considers the bogie frame flexibility is established. Field measurements were conducted to validate the reliability of the proposed model and the bogie frame’s modal vibration including the bending deformation of cross beams at 50 Hz can be observed. A comparison between the flexible bogie frame model and the traditional multi-body dynamics model is conducted to investigate the influences of the bogie frame’s flexibility on wheel-rail interactions. Then the numerical model of the rail weld joint is proposed to study the P2 resonance performance and the dynamic stress patterns of the bogie frame. A comparison of influences with different rail weld irregularities and parameter studies are conducted. Then the effects of fastener stiffness on P2 resonance frequencies are discussed. The results show that it is necessary to consider the bogie frame’s flexibility in simulations which will aggravate the wheel-rail vibrations. The short wavelengths in combination with a certain speed could induce the bogie frame’s modal vibration and large track supporting stiffness will threaten the running safety of the vehicle which may also contribute to the formation of wheel out-of-roundness. Besides, the limit values of the rail weld irregularities are discussed to provide a reference for rail surface grinding from different aspects.
