Design of an optimised wheel profile for rail vehicles operating on two track gauges
(Taylor & Francis, 2013-01)
This paper sets out an optimum synthesis methodology for wheel profiles of railway vehicles in order to secure good dynamic behaviour with different track configurations. Specifically, the optimisation process has been ...
Chatter avoidance in the milling of thin floors with bull-nose end mills: Model and stability diagrams
The milling of thin parts is a high added value operation where the machinist has to face the chatter problem. The study of the stability of these operations is a complex task due to the changing modal parameters as the ...
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 ...
Dynamic comparison of different types of slab tracks and ballasted track using a flexible track model
(Sage Publications, 2011-11)
The dynamic performance of a ballasted track and three types of slab tracks is analysed and compared by means of a comprehensive dynamic model of the train-track system, generated using two commercial analysis software ...
A rational fraction polynomials model to study vertical dynamic wheel-rail interaction
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 ...
On the influence of conformity on wheel–rail rolling contact mechanics
The aim of this work is to assess the effects of conformity on local contact related quantities at the wheel–rail interface such as traction distributions, subsurface stresses and frictional work distributions. For this ...
