“…If there is a positive eigenvalue, it is considered as a possible factor to induce polygonal wear, and the frequency-fixing mechanism is the corresponding mode frequency of the wheelset-track system with a positive eigenvalue. The model was further extended to study the reason for the polygonal wear of high-speed train wheels [77,78]. Moreover, the unstable vibration of the disc brake system of high-speed trains was thought to be a possible cause of wheel polygonisation from the viewpoint of frictional self-excited vibration [79].…”

“…Although many efforts have been made to better understand the formation mechanism of wheel polygonal wear, the formation mechanism of polygonal wear of high-speed train wheels in China is still not clearly understood. However, there are three viewpoints to explain the cause of wheel polygonal wear, including an excited resonance of the bogie [90,91], a bending vibration of the rail [86][87][88][89], and frictional selfexcited vibration of the wheelset-track system [77][78][79]. Although the formation mechanism is not clear, the development of wheel polygonal wear is well controlled by using a tread cleaner, especially the new-generation highspeed EMU of the Fuxing series.…”

Polygonisation of railway wheels: a critical review

et al. 2020

View full text Add to dashboard Cite

Polygonisation is a common nonuniform wear phenomenon occurring in railway vehicle wheels and has a severe impact on the vehicle–track system, ride comfort, and lineside residents. This paper first summarizes periodic defects of the wheels, including wheel polygonisation and wheel corrugation, occurring in railways worldwide. Thereafter, the effects of wheel polygonisation on the wheel–rail interaction, noise and vibration, and fatigue failure of the vehicle and track components are reviewed. Based on the different causes, the formation mechanisms of periodic wheel defects are classified into three categories: (1) initial defects of wheels, (2) natural vibration of the vehicle–track system, and (3) thermoelastic instability. In addition, the simulation methods of wheel polygonisation evolution and countermeasures to mitigate wheel polygonisation are presented. Emphasis is given to the characteristics, effects, causes, and solutions of wheel polygonisation in metro vehicles, locomotives, and high-speed trains in China. Finally, the guidance is provided on further understanding the formation mechanisms, monitoring technology, and maintenance criterion of wheel polygonisation.

“…With the rapid development of high-speed railways, friction and wear between wheels and rails and rolling contact fatigue damage are becoming more and more serious [1][2][3] . Such as the white layer will accelerate the peeling of the material [4] , and the wheel polygonisation wear will increase the vibration of the train [5] .Those problems shorten the repair and maintenance cycle of wheels and rails, and increase railway operating costs [6,7] . Therefore, higher requirements are put forward for the service performance of wheel rail materials.…”

EBSD Study on Proeutectoid Ferrite and Eutectoid Ferrite Refinement Mechanism of D2 Wheel Steel Under a Rolling Condition

In this paper, the SEM (with EBSD system) is used to study the re nement mechanism of proeutectoid ferrite (Pro-f) and eutectoid ferrite (Eut-f) of D2 wheel steel in a rolling contact. The results indicate that with the increase of the shear strain (γ<0.21), the dislocation density in the proeutectoid ferrite increased continuously, and the dislocation cells formed were uniformly distributed in the grains. Subsequently, the dislocation cell boundaries were changed into low-angle boundaries (LABs), and then the low-angle boundaries were gradually changed into the high-angle boundaries (HABs), and the average grain size was re ned from the original 8 μm to 710 nm. When the shear strain is at 0.21≤γ≤0.84, dislocation piled up occurred at the ferrite side of the interface of eutectoid ferrite/cementite, and the spatial misorientation between adjacent two eutectoid ferrites increased gradually, then the ferrite lamellar is divided into bamboo-like by the low-angle boundaries, and proeutectoid ferrite the grains are gradually re ned into equiaxed grain. When the shear strain is at 0.84<γ<3.314, the number of high-angle boundaries inside the eutectoid ferrite lamellar increased, and it is re ned into bamboo-like grains. The two kinds of ferrite grains are repeatedly re ned many times by the equiaxial grains "elongation-bamboo like re nement-elongation", which gradually reduced the size difference. As the shear strain further increases, the two kinds of ferrite are completely mixed into the same morphology, the dislocation density is dramatically reduced, and ultra-ne equiaxed grains about 110 nm is formed.

“…Wu et al [11] believed that there is a modal coupling resonance problem between the bogie wheelset and the frame around 580 Hz, which is closely related to the formation of wheel polygonal wear. Chen [12,13] put forward the viewpoint that wheel polygonal wear is caused by the frictional self-excited vibration of wheel-rail system in 2011. en, this viewpoint was taken to study the polygonal wear of the wheels of high-speed trains. e predicted results and the measurement data on-site can be well unified.…”

The wheels of power and trailer wheelset show different polygonal characteristics since their structures are obviously different. Therefore, the frictional self-excited vibration models of wheelset-track systems are established based on the viewpoint of the frictional self-excited vibration in reducing the wheel polygonal wear. Then, the motion stability of wheelset-track systems is studied by using the complex eigenvalue method. The results show that when the creep force between the wheel and rail is saturated, the unstable vibration frequency of the power wheelset is prone to induce 19-20th-order polygonal wear of the wheel, and the trailer wheelset is prone to induce 20-21th-order polygonal wear of the wheel. Meanwhile, the wheel polygonal wear can be effectively alleviated through changing the gearbox position of the power wheelset. And avoiding disc braking at high speeds can suppress the occurrence of wheel polygonal wear. In addition, the development tendency of wheel polygonal wear can be reduced by increasing the Young’s modulus of the brake pad, but Poisson’s ratio has little effect on the development tendency.
