This article deals with the dynamic analysis of train-track-bridge interaction system using the finite element method. In this interaction system, each four-wheelset vehicle in the train is modeled by a mass-spring- damper system with 10 degrees of freedom; the rails and the bridge decks are modeled as a number of Bernoulli-Euler beam elements, while the elasticity and damping properties of the rail bed are represented by continuous springs and dampers. The equation of motion for the interaction system is presented in matrix form with time-dependent coefficients. The correctness of the proposed procedure is illustrated by a comparison with the numerical result from the existing literature. Several numerical examples are chosen to investigate the effect of two types of vehicle models, two types of bridge models and three damping values of bridge on the maximum dynamic responses of train, track and bridges.
