Excessive vibrations of railway vehicles induced by dynamic impact loadings have a
significant impact on train operating safety and stability; however, due to the complexity and …

Out-of-roundness in railway wheels, in particular polygonal wear resulting in regular, multi-
lobed, out-of-round wheels, has become a significant problem in recent years. It is of …

To study the effect of wheel polygonal wear (WPW) on temperature and vibration behaviours
of a high-speed train braking system, a rigid-flexible coupled vehicle system dynamics …

Wheel polygonization poses severe threat to the operational safety of railway vehicles. To
improve running safety, condition monitoring of wheel polygonization based on axle box …

With the increasing speed of high-speed trains and the deteriorating operation environment
of axle-box system, the dynamic performance of axle-box bearing directly affects the stability …

The fracture of coil springs occasionally appears in rail vehicles, which may severely
jeopardise the train running safety. In this study, the fracture phenomenon of the locomotive …

Severe high-order polygonal wear has been found on metro train wheels of one metro line
in China, which causes considerable vibration of vehicle components and disturbing interior …

Nonlinear dynamic behavior of a new mesh-type rail pad on the vehicle-slab track coupled
system is investigated considering the influences of frequency and amplitude dependence …

Polygonal wear of railway wheels will accelerate the failure of critical structure. It is of great
significance to monitor their state in service. However, affected by the frequently changed …

Violent interactions between wheel and rail caused by the polygonal wheels can strongly
