The use of contact lookup tables is widely used in multibody railway simulations to increase
the computational efficiency. However, due to simplifying assumptions the use of contact …

This paper presents a review of recent research investigations on the computer modelling of
flexible bodies in railroad vehicle systems. The paper will also discuss the influence of the …

Various vibration-attenuating slab tracks have been introduced into urban railways to
minimize the negative effects of train-induced ground vibration and noise. However …

Nowadays, with various advancements in the railway industry and increasing speed of
trains, the design of railway tracks and vehicles has become vitally important. One of the …

In this work, we assessed the capabilities of a method that uses a multibody system
description of railway vehicles based on a moving coordinate system in combination with …

In order to model a long flexible body subjected to a moving load within multibody systems,
the flexibility can be considered by using a special floating frame of reference approach. In …

This study investigates the simultaneous effects of unsupported sleepers and rail random
irregularities on track displacement and wheel load reduction, by means of numerical …

This paper presents a procedure that makes use of a particular formulation based on the
trajectory coordinate system (TCS) approach, which is specific of ground vehicles, to …

This paper is a summary of the research done at the University of Seville in the field of
railway dynamics in the last 20 years. This research is separated in this paper in two …

Parameter identification of a railroad vehicle is very important to have a precise vehicle
model. A first step in this parameter identification can be to get information concerning …
