Beam on elastic foundation theory is widely employed when studying railway track
behaviour, for applications such as track dynamics, and noise and vibration. At a basic level …

This work reviews the main techniques to model dynamical systems with contact-impact
events. Regularized and non-smooth formulations are considered, wherein the fundamental …

This paper surveys advances in the understanding and modelling of wheel–rail creep
forces. The main focus is placed on tribological aspects, for which significant progress was …

The wheelset-gear box of high-speed train is the typical unsprung mass serving in the
complex excitation environment. To investigate the independent and compounded …

The standard model-based approach for predicting wheel wear consists of four main sub-
modules: a macro vehicle-track model, a normal wheel-rail contact model, a tangential …

The development and implementation of wheel-rail contact models in multibody codes are
two active research topics, aiming at improving the accuracy of numerical results and …

Tread wear and rolling contact fatigue (RCF) damage propagated on railway wheels are the
two extremely important focal points as they can tremendously deteriorate wheel/rail …

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 …

The development of wheel–rail contact models is an active topic of railway research with the
dual objective of improving the accuracy of multibody simulations and reducing its …

This paper reports a new non-Hertz normal contact model for the engineering computations
such as vehicle-track dynamics and wheel-rail damage prediction. The model is developed …
