Study on Potential Evolution Mechanisms of OOR Wheels at Trams

Zehetbauer, Florian / Edelmann, Johannes / Plöchl, Manfred / Magerl, Florian

This paper presents a basic study on a potential formation mechanism of wheel polygonization at trams. It was found that wheelset vibrations may occur at negotiating curves with small radius of curvature, caused from a self-excitation mechanism. To investigate the influence of system parameters relevant for the appearance of these vibrations, a representative system model is set-up in SIMPACK. Considering the falling friction effect in the creep force–creepage characteristics at high values of lateral creepage, results reveal that the flexibility of both the wheelset and the resilient wheels is essential. Recurring periods of respective vibrations at constant velocity could be able to promote wheel polygonization.
