Abstract

L'invention concerne un procédé permettant de déterminer le risque de déraillement de véhicules ferroviaires au moyen d'une section de mesure constituée d'une rangée d'éléments de mesure placés sur les rails, lesquels éléments enregistrent des effets de force et envoient des signaux électriques correspondants à un dispositif d'analyse de signaux électronique. Selon la présente invention, des éléments de mesure, placés sur le bord extérieur du champignon de rail et sur les deux bords du patin du rail, fournissent des signaux indiquant le mouvement du rail dans le sens horizontal; des éléments de mesure des deux côtés de l'âme du rail enregistrent des contraintes longitudinales sur le rail et un élément de mesure, supportant le patin du rail, enregistre des forces horizontales et verticales appliquées sur le rail et se déplaçant dans le sens horizontal en fonction du point de contact de la roue, un réseau continu d'informations étant ensuite formé dans le dispositif d'analyse à partir des signaux transmis, lequel réseau indique des instabilités et des forces de déplacement de rail.
