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 …

Multibody dynamics deals with the study of mechanical systems composed of multiple
bodies, whose motion interactions are governed by the presence of kinematic constraints …

The wheel-rail contact modeling problem assumes a preponderant role on the dynamic
analysis of railway systems using multibody systems formulations. The accurate and efficient …

The track has a crucial role in the performance of the rail network as it provides support and
guidance to the rolling stock. During train operation, the vehicle-track interaction generates …

The railway tracks are composed of steel rails that are supported by the infrastructure
through sleepers, which are generally assembled with a fixed separation between them …

Train operations generate high impact and fatigue loads that degrade the rail infrastructure
and the vehicle components. Rail pads are installed between the rails and the sleepers in …

Railway bogies of the Y25 family are the most common type of freight bogies used in
Europe. However, this family of bogies presents poor curving performance and a derailment …

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 …

Research and development of technology for railways has found new impetus as society
continues to search for cost effective and sustainable means of transport. This tasks …
