Numerical and Experimental Analysis of Transfer Functions for On-Board Indirect Measurements of Rail Acoustic Roughness. In : Noise and Vibration Mitigation for Rail Transportation Systems

Résumé

The paper presents some results concerning the development of a multi-sensor hybrid approach for measuring rail roughness using acoustic and vibration signals measured on-board. The main objective of the system is to provide better input data for noise mapping and maintenance strategies. Several improvements to existing systems are proposed, based on the analysis of transfer functions. First numerical and experimental results are discussed.
