When dealing with railway systems, wheel-rail contact forces play a key role in vehicle dynamic behaviour and have a strong influence on safety, comfort, noise and wheel/rail wear. Contact mechanisms are particularly important when low radius curves are considered, like those which are typical of urban transportation. This paper is intended to analyse vehicle dynamic behaviour in sharp curves, with particular reference to derailment conditions, by means of a mathematical model that includes a full schematisation of the vehicle and an accurate description of the contact forces.

Abstract
When dealing with railway systems, wheel-rail contact forces play a key role in vehicle dynamic behaviour and have a strong influence on safety, comfort, noise and wheel/rail wear. Contact mechanisms are particularly important when low radius curves are considered, like those which are typical of urban transportation. This paper is intended to analyse vehicle dynamic behaviour in sharp curves, with particular reference to derailment conditions, by means of a mathematical model that includes a full schematisation of the vehicle and an accurate description of the contact forces.File in questo prodotto:
