Measurement and Analysis of Noise Generated in a Tram Rail Wheel Contact

摘要

The interaction between wheel and rail is the main source of noise in a tram that moving on the rolling track. Wheel and rail irregularities are the causes that initiate dynamic forces and vibrations. Noise is the result of vibrations generated due to defects located on the contact of these surfaces. Rolling noise levels reduction can be achieved by improving contact surface condition mainly by wheel bogies reshaping. This paper presents the assessment of noise and its measurement for a series of noise measurements of in-service trams, taken within the Timisoara city area.
