A contact mechanics study of 3D frictional conformal contact
; Santamaría Manrique, Javier
; García Vadillo, Ernesto ; Correa García, Nekane (Elsevier, 2018-03)
A contact mechanics study of three-dimensional conformal contact with friction is presented, based on numerical calculations with Finite Element models and an extension of Kalker's exact contact theory which takes into ... -
A rational fraction polynomials model to study vertical dynamic wheel-rail interaction
Correa García, Nekane; García Vadillo, Ernesto ; Santamaría Manrique, Javier ; Gómez López, Josu (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 ... -
Design of an optimised wheel profile for rail vehicles operating on two track gauges
Santamaría Manrique, Javier; Herreros, Jesús; García Vadillo, Ernesto ; Correa García, Nekane (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 ... -
Modelling rail corrugation with specific track parameters focusing on ballasted track and slab track
Oyarzabal de Celis, Olatz; Correa García, Nekane ; García Vadillo, Ernesto ; Santamaría Manrique, Javier ; Gómez López, Josu (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 ... -
On the influence of conformity on wheel–rail rolling contact mechanics
; Santamaría Manrique, Javier; García Vadillo, Ernesto ; Correa García, Nekane (Elsevier, 2016-07)
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 ... -
On the non-proportionality between wheel/rail contact forces and speed during wheelset passage over specific welds
Correa García, Nekane; García Vadillo, Ernesto ; Santamaría Manrique, Javier ; (Elsevier, 2018-01)
This study investigates the influence on the wheel-rail contact forces of the running speed and the shape and position of weld defects along the track. For this purpose, a vertical dynamic model in the space domain is used. ... -
On the study of train-track dynamic interactions caused by rail welds on discrete supported rails
Correa García, Nekane; García Vadillo, Ernesto ; Santamaría Manrique, Javier ; Gómez López, Josu (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 ... -
Predicting rail corrugation in a real line by means of a fast non-linear vertical and lateral model
Robles Ampudia, Rakel; Correa García, Nekane ; García Vadillo, Ernesto ; (Elsevier, 2023-07)
This work is the result of a problem of premature development of rail corrugation found on a new metro line. As urgent solutions, a rail grinding was carried out and friction modifier started to be applied. Experimental ...
