OPTIMIZATION OF THE TRAM TRANSPORTATION NETWORK OF BUCHAREST CITY THROUGH TRAM NOISE EMISSION STUDY

摘要

The article presents the research results for the constructive optimization of the tram embankment of Bucharest network. There have been chosen more constructive solutions for the embankment and rails following the rehabilitation of the tram network. On the occasion of the noise mapping for Bucharest city there have been accomplished the first studies regarding the trams' noise. Later there have been realized additional measurements in order to follow the analysis of the interaction in dynamic conditions between embankment - rail type - vehicle and also its correlation with the acoustic emission. In this article is presented the measurement methodology and also a synthesis of the experimental results obtained through the movement of different vehicles types, considered to be illustrative for the present trams' fleet, on different types of embankment and with constant speed.
