Le vibrazioni in campo ferroviario: analisi f.e.m. dell’interazione convoglio-sovrastruttura-terreno

Abstract

This paper describes the formulation and application of a finite element method model that simulates the generation and propagation of train-induced vibrations into track-ground system. The F.E.M. model accounts for the interaction between ground, railway, shape of cross-section and train speed. The aim of this research is the evaluation of the influence of each factor on vibrational phenomena.
