An Investigation of Rolling Noise of Conventional Meter-Gauge Railway Lines

Abstract

Rolling noise is generated by the vibration of wheels and rails due to the excitation force, caused by roughness on the surfaces of the wheels and rails. Theoretical models, such as TWINS model, have been widely used to gain better understandings of rolling noise. In this paper, the model is applied to Japanese railways and validated in terms of vibration and noise. Through the validation work, it is shown that the predictions show a close correlation to the measurements. For the noise spectra, the contribution of the rail to rolling noise is found to depend on the type of tracks.
