Comparison of the Accuracy of Several Bridge/Rail Coupling Models with Experimental and Numerical Results

Current demand of faster, comfortable and competitive railroad infrastructure results in the removal of older jointed rails in order to replace it with continuously welded rails (CWR). These are used for their ability to create a comfortable joint-free track supporting the minimization of dynamic 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, isn't currently sufficient, because the values vary immensely. Therefore an extensive experimental measurement was done on the railway bridge near the town of Děčín with the intention of improving the current state of knowledge of the CWR/bridge interaction. The main goal of this paper rests on performing a numerical analysis using various numerical models of the coupling interface and the subsequent comparison with the experimental and prescribed values. The complex overview with the results of the experimental evaluation, numerical model verification and data comparison is offered in this paper, including some interesting conclusions as well. The conclusions of the paper provide advice for better numerical modelling of the bridge/track interaction.
