Comparison of the accuracy of several bridge/rail coupling models with experimental and numerical results

Popis výsledku v původním jazyce

Current demand of faster, comfortable and competitive railroad infrastructure results in the removal of older jointed rails in order to place the continuously welded rails (CWR) instead. These are used for their ability to create a comfortable joint - free track supporting the minimization of dynamical impact on both the substructure and the vehicle itself. Unfortunately the placement of CWR is limited for bridges due to its interaction with the supporting structure that is coupled with the rail. The scientific data, needed for simple and reliable analysis, aren't currently sufficient, because the values vary immensely. There was therefore done an extensive experimental measurement on the railway bridge near the town Decin with the intention of improving cur rent state of knowledge of the CWR/bridge interaction. The main goal of this paper rests on performing numerical analysis using various numerical models of the coupling interface and the subsequent comparison with the experimental
