Stochastic modelling of rail fatigue

Résumé

The dynamical response of a train rolling on a real track depends on several parameters. Most of them cannot be accurately identified and have to be considered as uncertain implying that the wheel-rail contact parameters cannot be completely characterized using deterministic models. The aim of this paper is the construction of a probabilistic model of the rail fatigue life considering the track geometry and the rail wear as random fields indexed by the space (curvilinear abscissa of the track) and statistically representative of the considered railway network.
