Digital twin
In the Digital Twin research workshop at the Chair of Railway Track Engineering, numerical simulations can be carried out using CAD, FEM, DEM and MBS software. Typical applications include BIM simulation, strength verification and design optimization on various track components and systems, contact analysis between sleepers and individual ballast stones, wheel-rail contacts and vehicle-track interactions. An existing model database including various vehicles and track constructions, special structures such as switches and transition zones is available. All models are verified by extensive laboratory and track measurements.
