A decoupling method for wheel-rail contact forces of heavy-duty trains based on big data and neural networks

open access: yes机车电传动
To accurately identify and predict wheel-rail contact forces during the operation of heavy-duty trains, this paper proposes a novel method of decoupling and predicting these forces based on big data related to non-contact strain at the wheel periphery ...

The Impact of Hollow Wear on the Stability of High-Speed Railway Vehicles

open access: yesApplied Sciences
Hollow wear on wheels is a common form of surface damage often observed in high-velocity vehicles. It is widely recognized that hollow wear of the wheel tread degrades the dynamic performance of rail vehicles, especially in the issue commonly referred to

Fast non-Hertzian wheel-rail thermal contact models integrated with tread brake in train dynamic simulations

open access: yes
This paper presents an integrated simulation of wheel-rail thermal interactions under tread braking, using fast finite difference models and non-Hertzian contact. ANALYN is used to improve contact patch accuracy and rail chill effect prediction.

Crack path modelling in railway wheel under rolling contact fatigue

open access: yesApplied and Computational Mechanics, 2015
A computational model of crack path for two-dimensional primary crack situated in a railway wheel rim is designed. The railway wheel rim is placed on the wheel disc of railway wheel with interference fit.
