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 ...
Investigation of acoustic transmission beneath a railway vehicle by using statistical energy analysis and an equivalent source model

Li, Hui; Thompson, David; Squicciarini, Giacomo; Liu, Xiaowan; Rissmann, Martin; Denia, F. D.; Giner Navarro, Juan (Elsevier, 2021-03)

[EN] An approach is presented for modelling the noise propagation beneath the train floor and this is applied to rolling noise sources. It is assumed that the sound incident on the train floor is made up of a direct and a ...
Measurements and modelling of dynamic stiffness of a railway vehicle primary suspension element and its use in a structure-borne noise transmission model

Liu, Xiaowan; Thompson, David; Squicciarini, Giacomo; Rissmann, Martin; Bouvet, Pascal; Xie, Gang; Martínez Casas, José; Carballeira, Javier; Lopez Arteaga, Inés; Garralaga, Miguel A.; Chover, José A. (Elsevier, 2021-11)

[EN] The noise inside railway vehicles is transmitted by both structure-borne and airborne paths and, although there are many sources, the rolling noise is often the most important. This paper focuses on the structure-borne ...
Method for obtaining the wheel-rail contact location and its application to the normal problem calculation through CONTACT

Baeza González, Luis Miguel; Thompson, David J.; Squicciarini, Giacomo; Denia, Francisco D. (Taylor & Francis, 2018)

[EN] This work presents a robust methodology for calculating inter-penetration areas between railway wheel and rail surfaces, the profiles of which are defined by a series of points. The method allows general three-dimensional ...
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 ...
