Abstrakt:
Track experiments and tests for railway vehicles are challenging tasks. In order to realize methods and validate models which are developed for railway vehicle systems, roller-rig test equipments are widely used. In this study, a torsional dynamic model of a tram wheel test stand, which has a wheel on roller configuration and has been used for research purposes in faculty of transport engineering, university of Pardubice for many years, is proposed. Numerical simulations are validated by the measurements taken from this roller-rig. This model includes solution to geometrical, normal and tangential problems for wheel-rail interface and models of electric motors. Comparison with measurements shows that this modelling formalism is promising to test and verify proposed methods for the test stand and railway vehicle systems.
