Analysis of vibrations in a modeled ballasted track using measured rail defects

Real Herráiz, Julia Irene; Asensio Serrano, Tamara; Montalbán Domingo, María Laura; Zamorano, Clara (Research Center of the Public Institution "Vibromechanika", 2012-06)

Vibrations caused by trains and transmitted to the ground and structures nearby are a known source of problems related to railways. Therefore this phenomenon should be studied in detail to avoid a negative impact in the ...
Análisis de la solución de vía ferroviaria en balasto frente a vía en placa y montaje de superestructura en la línea de alta velocidad Madrid-Zaragoza-Barcelona-frontera francesa. Tramo puente de Ebro-Lleida. Construcción y montaje de la vía en placa

Cases Villar, Javier (Universitat Politècnica de València, 2015-09-15)

[EN] This thesis makes a comparative analysis between slab track and ballasted track. The common part consists of geotechnical, topographical, plotted, receipt of track and axle exchanger annexes. The study focuses on ...

Análisis de la solución de vía ferroviaria en balasto frente a vía en placa y montaje de superestructura en la línea de alta velocidad Madrid-Zaragoza-Barcelona-frontera francesa. Tramo puente de Ebro-Lleida. La explotación y el mantenimiento de la vía en placa y la vía sobre balasto

Marti Blazquez, Maria del Mar (Universitat Politècnica de València, 2016-09-08)

[EN] The aim of the Final Project is to do a viability study, both technical and financial, to implement slab track as a replacement to the current track on ballast. The line which we do the study about is the stretch ...
Comparison of the effect of different sleeper typologies and track layout on railway vibrations

Real Herráiz, Julia Irene; Zamorano, C.; Asensio Serrano, Tamara; Montalbán Domingo, María Laura (Argentinean Association of Computational Mechanics, Brazilian Association of Computational Mechanics, Mexican Association of Numerical Methods in Engineering and Applied Sciences, 2014)

[EN] The last years, ground vibrations have become an important study field due to the increase of the transports needs for society and its amount of running trains associated. The vibrations caused by trains are an important ...
Influence of track modelling in modal parameters of railway bridges composed by single-track adjacent decks

Sánchez Quesada, Juan; Moliner, E.; Romero, A.; Galvín, P.; Martínez-Rodrigo, M.D. (Editorial Universitat Politècnica de València, 2022-05-11)

[EN] A significant number of railway bridges composed by simply-supported (SS) spans are present in existing railway lines. Special attention must be paid to short to medium span length structures, as they are prone to ...
Lattice isomorphisms between spaces of integrable functions with respect to vector measures

Fernández Carrión, Antonio; Mayoral, F.; Naranjo, Francisco; Sánchez Pérez, Enrique Alfonso (THETA FOUNDATION, 2011)

[EN] The study of vibrations induced by a passing train is of utmost importance to understand better this phenomenon and to design efficient mitigation measures. Within all the techniques used to model vibrations, finite ...
Railway traffic induced vibrations: comparison of analytical and finite element models

Real Herráiz, Julia Irene; Asensio Serrano, Tamara; Montalbán Domingo, María Laura; Zamorano, Clara; Real, T. (Research Center of the Public Institution "Vibromechanika", 2013-12)

The recent increase in the use of the railway and the establishment of more restrictive policies of harmful environmental effects of railway transport highlights the need to investigate ground vibrations related to trains. ...
