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.

“…Many of the studies on the problem of wear of a wheel to create a polygon-shaped wheel have focused on the influence of track structure on the vehicle. 1,8–12 If we do not consider initially round wheels, the vibration frequency of the wheel/rail system is much lower than the natural vibration frequency of the monolithic roadbed track structure used for high-speed trains, however, polygonal wheel wear still affects high-speed trains. Hence, there must be many unknown factors that affect wear to create polygon-shaped wheels.…”

The reasons for wear of a wheel to create a polygon-shaped wheel on metro trains are analysed in this paper. Analysis of wear data leads to the conclusion that it is mainly structural vibration of the wheelset that causes the wear that creates polygon-shaped wheels. After analysing the characteristics of the structure and vibration of the vehicle, a model that considers wheelset flexibility is established. We then analyse the effects of flexible deformation of the wheelset on vertical force, creepage and creep force in wheel/rail rolling contact, and find that the main wheel wear frequency is 35.98 Hz. As for the question of how many faces the worn polygon-shaped wheel displays, we propose that the nature of the wear to create the polygon-shaped wheel depends on the average running speed of the vehicle. This relationship accounts for the apparent contradiction of a fixed vibration frequency and variable vehicle speed leading to wear to create a polygon-shaped wheel, and shows how a multi-faced polygon can be caused by a low-frequency vibration between wheel and rail.

“…This type of OOR has a periodic irregularity around the wheel circumference superimposed on the constant radius. The wavelength of the irregularity ranges from 0.1m to approximately one wheel circumference, while the amplitude is of the order of l mm [7,8] . Examples of periodic OOR with one, three and four periods around the wheel circumference have been found on wheels from ICE trains in Germany.…”

Abstract-Periodic non-roundness of railway wheels will cause a series of variety on vehicle/track coupling system dynamic responses. A coupling dynamics model of railway vehicle with out-of-round wheels and track was built based on ADAMS/Rail. The effect of periodic non-roundness of wheel on the dynamical behavior of the vehicle system was analyzed. The numerical results regarding the misalignments of the vehicle and wheelset, the vertical wheel/rail contact forces and the reduction in the wheelset loading are presented under the conditions in which the wheels are in out-of-round and the train speed is from 200 km/h to 350 km/h. The results show that the dynamical vertical wheel/rail interaction forces are much related to the wheel out-of-roundness status. The critical range of the wheel outof-roundness is determined according to the traditional criterion of wheelset loading reduction for safely running estimation. It's pointed out that out-of-round railway wheels can be detected by wheel/rail interaction force real-time monitoring system to guarantee safety and to minimize costs for repair and maintenance.Index Terms-High speed train wheelset; out-of-round wheel; wheel/rail impact vibration; ADAMS/Rail
