A framework to predict the airborne noise inside railway vehicles with application to rolling noise

Li, Hui; Thompson, David; Squicciarini, Giacomo; Liu, Xiaowan; Rissmann, Martin; Bouvet, Pascal; Denia, F. D.; Baeza González, Luis Miguel; Martin Jarillo, Julian; Moreno Garcia-Loygorri, Juan (Elsevier, 2021-08)

[EN] A framework is described for predicting the airborne noise inside railway vehicles which is applied to rolling noise sources. Statistical energy analysis (SEA) is used to predict the interior noise by subdividing the ...
A linear non-Hertzian unsteady tangential wheel-rail contact model

Baeza González, Luis Miguel; Bruni, Stefano; Giner Navarro, Juan; Liu, Binbin (Elsevier, 2023-03)

[EN] The increase in computational capacity has considerably reduced the use of linear models for wheel/rail tangential contact, being currently replaced by theories that adopt non-linear formulations able to address the ...
A model of a rotating railway wheel for the prediction of sound radiation

Andrés-Ruiz, Víctor Tomás; Martínez Casas, José; Denia, F.D.; Thompson, D.J. (Elsevier, 2023-06-09)

[EN] The axial symmetry of a railway wheel is taken into account to expand its vibrational response around the circumferential direction using Fourier series. This allows the vibroacoustic problem of the wheel to be ...
Desarrollo e implementación de modelos vibro-acústicos unidimensionales de la vía ferroviaria para la reducción de ruido

Estellés Gil, Alba (Universitat Politècnica de València, 2020-07-31)

[ES] En la actualidad, la contaminación acústica proveniente de la vía es uno de los mayores inconvenientes del sector ferroviario. Por ello, se están desarrollando modelos dinámicos más precisos para estudiar con detalle ...
Desarrollo y validación de técnicas para el cálculo de las frecuencias críticas de la vía ferroviaria

Rincón Contel, Fernando (Universitat Politècnica de València, 2021-09-07)

[ES] La vía ferroviaria, al tratarse de un sistema periódico de dimensiones infinitas, constituye un problema de características singulares dentro de la Ingeniería Mecánica. Al contrario que la mayor parte de problemas de ...
Development of innovative methodologies to reduce railway rolling noise through Genetic Algorithm-based shape optimization techniques

Garcia Andrés, Xavier (Universitat Politècnica de València, 2021-03-15)

[ES] El ruido de rodadura es un fenómeno producido debido a la interacción entre la rueda y el carril e inducido por las pequeñas irregularidades existentes en la superficie de ambos. Dichas irregularidades, conocidas como ...
Influence study of rail geometry and track properties on railway rolling noise

Andrés-Ruiz, Víctor Tomás; Martínez Casas, José; Denia, F. D.; Thompson, D. J. (Elsevier, 2022-05-12)

[EN] Wheel/rail interaction generates an excitation due to the roughness present on the surface of both components that produces vibration and consequently rolling noise. In this work, the railway track properties that ...
Minimización de Rolling y Squeal noise en ruedas ferroviarias mediante optimización multiobjetivo

Lamoncha Navarrete, Eva (Universitat Politècnica de València, 2019-09-26)

[ES] La contaminación acústica generada por vehículos ferroviarios es un problema que afecta a la salud de las personas y un importante obstáculo en la expansión de la red de transporte. De entre los elementos responsables ...
Railway rolling noise mitigation through optimal track design

Andrés Ruiz, Víctor; Martínez Casas, José; Carballeira Morado, Javier; Denia Guzmán, Francisco; Thompson, D. J. (Editorial Universitat Politècnica de València, 2022-05-11)

[EN] The main goal of the present work lies in the identification of the railway track properties that influence acoustic radiation, as well as in the analysis of these properties for the reduction of sound levels. This ...
Rolling noise reduction through GA-based wheel shape optimization techniques

Garcia-Andrés, Xavier; Gutiérrez-Gil, Jorge; Andrés, Víctor Tomás; Martínez-Casas, José; Denia, Francisco David (Editorial Universitat Politècnica de València, 2022-05-11)

[EN] Railway rolling noise is nowadays a major source of acoustic pollution in urban areas, with nearly up to 12 million people daily affected in Europe by this phenomenon [1]. Hence, the search for ways of decreasing such ...
Using a 2.5D boundary element model to predict the sound distribution on train external surfaces due to rolling noise

Li, Hui; Thompson, David; Squicciarini, Giacomo; Liu, Xiaowan; Rissmann, Martin; Denia, Francisco D.; Giner Navarro, Juan (Elsevier, 2020-11-10)

[EN] In order to be able to predict train interior noise, it is first important to calculate the external sound pressure distribution on the floor, sidewalls and roof. This can then be combined with the transmission loss ...
Wheel shape optimization approaches to reduce railway rolling noise
