Abstract
With the development of continuous technological innovation, the railway transport is presented as an interesting alternative to the road traffic. Some drawbacks exist, one of the most problematic being certainly the vibrations induced by the railway traffic. The presented research wants to establish a reliable methodology in order to evaluate, from the design stage of a vehicle or of a track, the efforts transmitted by the vehicle to the track/soil system and consequently the level of vibrations in the surroundings. An analysis of the interaction between the track and the soil has been performed in order to show when the track/soil uncoupling can be assumed, with the aim of working in two stages. The first step is based on the vertical dynamic behaviour of the vehicle/track subsystem, taking into account any irregularity in the rail surface. For the soil subsystem (second step), recent publications showed that the finite/infinite element method can be an interesting alternative to boundary element method. The objective of this paper is to demonstrate the real benefit of the vehicle modelling in this kind of problem. Typical railway applications (Brussels tram, Thalys HST) are proposed, showing among others that significant reduction of ground vibration level can be obtained by modifying the dynamic characteristics of the vehicle.
