Propagation of vibrations induced on track: implementation of previsional models for low and high speed trains and comparison with experimental measurements

Overview & Synopsis

In recent years, the topic of vibrations in homes and workplaces has grown in importance. In order to reduce the vibrations due to road and rail traffic, several actions can be implemented, some of which are economically very costly. As a consequence, before implementing any mitigation measures, the availability of appropriate simulation tools able to characterize the effectiveness of the chosen solutions becomes more and more relevant. As part of this work, the development of a predictive software has been addressed, combined with experimental measurements, in order to assess with acceptable accuracy the vibration levels caused by rail transport trams, low-speed and high-speed trains. Predictions are obtained by characterizing waves propagation through the ground by the mean of separate approaches for low and high velocity trains. In this paper the results achieved has been presented, as well as the future potential of the activity.
