Abstract EN
The analysis of the contact steel/composite allowed to raise a diagnosis of the wears of soles in composite materials of brake of cars SNTF.
Real tests on in-use testing carried out on 32 cars including 256 clogs evolving in variable weather situation, during several shuttles on a route of 600 km allowed to study the on-line behavior of clogs in the course of exploitation and to raise a classification of the wears allowing to identify that it more frequent.
A comparison established between two wintry and summer (summery) periods explains the influence of the temperature on the wear of clogs.
Downstream, measurements of the physical and mechanical characteristics of the organic matrix C/C composite component of wagons brake shoe blocks show a characteristic dispersion mainly of the heterogeneous appearance of this type of material.
Some braking tests carried out on a tribometer, enabled to study the frictional behavior and identify the physical mechanisms of friction, which were activated with contact under severe braking loads
Abstract FRE
L’analyse du contact acier/composite a permis de dresser un diagnostic des usures des semelles en matériaux composites de frein des wagons SNTF.
Des essais en service réels effectués sur 32 wagons comprenant 256 sabots évoluant dans des conditions atmosphériques variables, sur un parcours de 600 Km ont permis d’étudier le comportement en ligne des sabots en cours d’exploitation et de dresser une classification des usures permettant de cerner celle la plus fréquente.
Une comparaison établie entre les deux périodes hivernale et estivale explique l’influence de la température sur l’usure des sabots.
En aval des mesures des caractéristiques physique et mécanique du composite carbone/carbone composant les semelles de sabots montrent une dispersion caractéristique de l’aspect hétérogène de ce type de matériau.
Des essais de freinage réalisés sur un tribomètre ont permis d’étudier le comportement en frottement et d’identifier les mécanismes physiques de frottement activés au contact sous sollicitations de freinage sévères.
