On the study of train-track dynamic interactions caused by rail welds on discrete supported rails
(Elsevier, 2014-06-15)
The paper studies the influence of rail weld dip on wheel-rail contact dynamics, with particular reference to freight trains where it is important to increase the operating speed and also the load transported. This has ...
A rational fraction polynomials model to study vertical dynamic wheel-rail interaction
(Elsevier, 2012-04)
This paper presents a model designed to study vertical interactions between wheel and rail when the wheel moves over a rail welding. The model focuses on the spatial domain, and is drawn up in a simple fashion from track ...
Modelling rail corrugation with specific track parameters focusing on ballasted track and slab track
(Taylor & Francis, 2011-11)
The objective of this paper is to compare 3 types of track (high performance ballasted track, STEDEF and AFTRAV) from the corrugation growth point of view. This work has considered different vehicle speeds and track ...
