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 …

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 …

The fatigue life of bogie frames directly determines railway vehicles' reliability and safety.
Assessing bogie frame fatigue life is a significant requirement for railway vehicle designs …

Serious wheel polygonal wear usually causes drastic wheel/rail interactions, which threats
the running safety of railway vehicles. This paper presents an investigation into the effect of …

Railway welded bogie is usually subjected to extremely complex fatigue loads, producing
huge failure hazard. However, only external excitations from the wheel-rail system are …

The wheel high-order polygonal wear leads to strong vibration/noise and deterioration of
railway systems, whose distribution is closely related to the seasonality and wheelset …

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 formation and development of wheel polygon wear (WPW) present significant
challenges to the safety of railway vehicle operations. It is widely accepted that WPW occurs …

Metro vehicle bogie frame is usually subjected to complex external excitations. The fatigue
damage accumulation of bogie frame is induced by multiple elements and may even lead to …

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 …
