RAYLWAY VEHICLE DYNAMICS AND THE SOIL VIBRATION ANALYSIS

The study of a running metro vehicle, exerted on this memory, was necessary to supply the procedure for a geotechnical characterization of the layer close to a metropolitan transport. In particular, the knowledge of these characteristics is fundamental for the determination and classification of the stresses applied by the rail vehicle to the track, which may increase structural impact on buildings, located near a railway line. For this purpose we propose a method for analyzing the results of simulations using MBS code, and, in particular, the kinematic and dynamic analysis of a rail system (vehicle-interaction wheel/rail/track-irregularities) with its vibrational characteristics (natural frequencies and amplifications of vertical and transverse loads acting on the rails). These results can then be used as input data for numerical applications (FEM) in determination of the characteristics of the transmissibility of vibration from the ground to the buildings.
