Noise reduction strategies for a light metro rail traction system

Abstract

The vibro-acoustic characterization of a light rail vehicle is presented. Object of the study is the "SIRIO" platform, ANSALDOBREDA's proposal for city transport on rails. The approach followed can be distinguished in two different moments: on board measurements and pass by measurements. Both measurements were performed in order to separate traction noise (most relevant sources at low speed) from rolling nois
