During the MBS Tech Days 2021, Jonas Vuitton and Max Schischkoff from the TU Berlin held a presentation called "Modelling and Application of a Y25 Freight Bogie in MBS".
In their presentation, Jonas and Max address how freight wagons are generally regarded as the most simply constructed rail vehicles in terms of running technology. Although they usually have one spring stage only, and the damping is ensured by friction elements, the modeling of freight wagons in MBS is rather complex. The parameters of the running gear depend on the maintenance status and the construction tolerances of individual vehicles and are difficult to determine. The modularly structured model of the Chair of Rail Vehicles of TU Berlin allows investigations of the dynamic behavior of four-axle freight wagons with the most common European bogie Y25. This model has been used in several projects and continuously improved in terms of accuracy and computing performance. It is integrated into an in-house MATLAB-based framework allowing multi-dimensional parameter variations. Exemplarily, a use case for the detection of rail obstacle roll-over incidents is presented. The model is used for the preliminary investigation of the derailment safety during the measurement campaign, and the relevance of simulations for rail obstacle roll-over incidents is evaluated.
Jonas Vuitton is a Research Assistant at the Chair of Rail Vehicles at the Technical University Berlin. His main research topics are on the dynamics of rail vehicles, especially using numerical simulation, and the digitization of the maintenance of rail freight operations, implementing data-based maintenance strategies. Jonas's research focuses on the rail freight system at the interface between vehicles and operations.
Max Schischkoff works as a Research Assistant at the Chair of Rail Vehicles at the Technical University Berlin. His main topics of research are the dynamics of rail vehicles using numerical simulations and the Digital Automatic Coupler (DAC) in rail freight transport. Max's reMax'sh focuses on the rail freight system at the interface between vehicles and operations.
