    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 ...

    A state-of-the-art review of curve squeal noise: Phenomena, mechanisms, modelling and mitigation 
    Squicciarini, G.; Thompson, D.J.; Ding, B.; Baeza González, Luis Miguel (Springer, 2018)
    [EN] Curve squeal is an intense tonal noise occurring when a rail vehicle negotiates a sharp curve. The phenomenon can be considered to be chaotic, with a widely differing likelihood of occurrence on different days or even ...

    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 ...

    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 ...
