“…However, they neglected the influence of the gear transmission system. Wang et al [60][61][62] performed numerous simulations to investigate the effects of wheel defects, such as polygonisation and flat, on the dynamic performance and fatigue reliability of the gearbox housing. They developed a powerful numerical model that included the vehicle-track coupled dynamics, flexibility of the wheelset and gearbox, and gear transmission system.…”

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.

“…Meanwhile, the influence of polygonal wear upon static and dynamic imbalances, using a dynamic model based on flexible deformation of the wheelset was invested by Meinke [9]. Zhiwei Wang [10,11] studied the dynamic performance of a gearbox housing under the effect of wheel polygonal wear. Xingwen Wu [12,13] investigated the effects of polygonal wear and wheel flats on the wheelset using a coupled vehicle-track dynamics model including a flexible wheelset.…”

“…In practice, the TRBs of the axle-box interact dynamically with the connected components of high-speed trains. Some authors realised that it is important to couple the vehicle and track together due to the intensified wheel-rail interactions as the train's running speed increases [22,23], especially if wheel defects occur [11,12]. Moreover, the vibration of vehicle components is significantly influenced by wheel polygonal wear and likewise the life of the bearing is directly related to its dynamic load environment [24].…”

The axle-box bearing is a key component of a high-speed train, providing a safety-critical load path for axial and radial forces transmitted between the wheel-rail interface and the bogie frame. Failure of axle-box bearings can directly affect operational and safety performance of the train, and therefore understanding their operating state is key to predicting potential failure modes and planning maintenance interventions. In this study, a three-dimensional vehicle-track coupled dynamics model, with the inclusion of the axle-box bearings has been developed. Based on the bearing's structural properties and operating characteristics, the coupling effects of the vehicle components relative to the bearing are considered. The model also takes a number of non-linear factors into account, such as time-varying bearing stiffness, bearing clearance, wheel-polygonal wear and the non-linear wheel-rail contact forces. Dynamic analysis of the model has been carried out through numerical simulations that consider different amplitudes and harmonic orders of measured and idealised polygonal wheel wear. Both model analysis and validation was supported by field tests performed on a high-speed rail line. Simulation results show that the amplitude of rolling contact forces of the axle-box bearing increases with vehicle speed and the amplitude of polygonal wear. However, the influence of wear upon the axle-box bearing is found to be small in the low-speed range, but at higher operating speeds, polygonal wear begins to lead to a rapid increase in bearing contact forces and the potential for degradation. As a result of vehicle operations, both high order (17 th to 20 th order) and lower order (1 st to 4 th order) wheel polygonal wear patterns are generated. The former's influence on axle-box bearing forces is more significant. Hence, the identification and rectification of this order of wear should form part of maintenance practice and potentially also be considered in the design of axlebox bearings for high-speed trains.

“…The similar concept has been adopted in many studies of railway dynamics [18][19][20]. Besides, the poor wheel conditions contribute to the enhancement of wheel-rail interactions and cause the vehicle-track components fatigue failure [21,22]. Although many researchers focused on understanding railway vehicles and the dynamics performance of TRBs, the coupling effects between them are yet to be considered.…”

A three-dimensional, vehicle-track coupled dynamics model has been developed that accurately reflects the dynamic performance of a high speed train during operation. The model includes novel elements that allow detailed consideration of the transmission system and axle box bearings. Within these novel elements a number of nonlinear factors have been modelled, including gear time-varying mesh stiffness, bearing stiffness, bearing clearance, and wheel-rail contact. The model has facilitated a detailed analysis of the vibration and temperature environment of the critical axle box bearing of high speed trains. The proposed model was extensively validated by comparing the results of the simulation with those of experimental tests. The temperature characteristics of the axle box bearing of the motor car and the trailer were analyzed and the resultant mathematical model was subsequently validated through long-term experimental field tests. Additionally, the relationship between vibration and temperature was analyzed during operation. The results indicated that the loads acting on the axle box bearing closest to the gearbox of the motor car (bearing 1) are significantly higher than those distant to the gearbox (bearing 2), the cause being differences in structural stiffness, which also lead to higher local temperatures. Moreover, the roller-outer raceway contact force and temperature of Bearing 1 was also higher than that of bearing 2. Conversely, when considering the trailer car, the dynamic performance and hence vibration and temperature environment of bearing 1 and bearing 2 were almost identical, this being a result of similarities in their structure and mounting arrangement. In summary, the work demonstrates that the temperature and vibration characteristics of the axle box bearings and their assessment can be used to aid in the effective design and maintenance of high-speed trains, together with the development of remote condition based monitoring (RCM) systems.
