Abstract
In this paper, various two-dimensional (2D) models of train-bridge dynamic interaction are established using multibody dynamics theory and beam theory. The models are solved using the Newmark-đť›˝ method, a common implicit integration method for structural dynamics. The research gives a description of the effect of train parameters on the train-bridge dynamics using a full 2D train model. By clearly describing the train and bridge models used, an attempt will be made to accurately describe the physics behind the models. The result of the simulations describe the differences between different models, after which the effects of various train parameters on the midpoint displacements are illustrated.
