Abstract
The report presents the second part of the Benchmark test which was part of the DFG-priority program ”System dynamics and long-term behaviour of vehicle, track and subgrade” . Ballasted tracks and slab track systems on homogeneous and layered half-space are examined. Different track systems, different soil conditions, different calculation methods and a number of parameters were investigated. For example the complete or the relaxed boundary condition between the ballast and the soil was found to be of importance at low frequencies. The type and the values of the material damping of the pad element has great influence on the flexibility of a slab track. Generally it has to be noted, that the flexibility functions of all analyzed systems are described sufficiently well by all models.
