Dynamic Analysis of a Railway Vehicle in Real Operation Conditions Using a New Wheel-Rail Contact Detection Model

This paper develops and implements a methodology to create three-dimensional track models, including the permutations resulting from track irregularities. The authors apply a new method using wheel and rail surface parameterizations to identify multiple contact points. This method allows lead and lag flange contact, required to study derailment and switches. The formulation can be used for any kind of wheel or rail profile and still be computationally efficient without requiring lookup tables. The method is applied to study the ML95 vehicle in a straight track with experimentally measured track irregularities. A comparison of the dynamic analysis results from this methodology and model with the results available from experimental data and the commercial program ADAMS/Rail indicates that the proposed model and methodology are both qualitatively and quantitatively correct.
