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 …

A wire bracket is a cantilever structure connected to the axle box of a high-speed train. Its
force is complex and it is prone to vibration fatigue failure. Combined with fracture analysis …

Considering not only the stochastic track irregularity and the possible effect of stochastic
parameter excitation, but also the time delay of spring, that is, its response is in place, but the …

An accurate wheel-rail contact theoretical model is crucial for predicting wheel-rail wear and
rolling contact fatigue. The plastic damage occurs frequently in the high-speed wheel-rail …

Modelling wheel-rail interaction at short-wave irregularities is an important issue under the
context of vehicle-track system dynamics for analyzing and preventing severe impact. The …

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 …

The geometric irregularities of rail welds and polygonal wheels are common defects
observed in high-speed railways, leading to the generation of high-frequency impact forces …

Severe wheel polygon will cause the strong repeated wheel-rail excitation, accelerating the
failure of vehicle key components. Nevertheless, the traditional spectral estimation methods …

The presence of shortwave irregularities on wheel and rail surfaces is a critical concern in
vehicle-track interaction. This paper examines the influence of shortwave irregularities on …

Polygonized wear of wheel is a three-dimensional wear state which includes circumferential
periodic wear and lateral hollow wear. When polygonized wear of wheel occurs, wheel-rail …
