Abstract

A 3D explicit finite element model is utilised to analyse the contact situation in the switch panel. Especially, the diverging switch rail is subjected to high lateral contact forces, which leads to a degradation of this component. The location of the impact point at the switch rail is a decisive parameter which is highly affected by the turnout geometry and the passing vehicle. This work evaluates the influence of several wheel parameters, namely the wheel profile, wheel yaw angle and lateral wheel-set displacement on the initial impact position and the magnitudes of the lateral contact force. The analysed turnout geometry is a standard 60E1-500-1:12 turnout with a singe S1002 wheel rolling over it. It is shown that the critical region where initial impacts at the switch rail are likely to occur is located between 1.5 and 3 m from turnout entry for this turnout geometry.
