Multibody models for the study of the vehicle-track interaction used by railway companies consider mainly rigid components. These models are characterized by small number of degrees of freedom allowing real time calculations in low frequency ranges, but these models do not properly estimate real interaction forces because of the strong hypothesis of the components rigidity. These models need to be improved by taking into account the components flexibilities by coupling finite elements analysis with multibody dynamics simulations. The main objective of this study is to develop the multibody models of a railway vehicle and track with flexible wheelsets and flexible rails in order to improve the prediction of vehicle-track interaction forces....
