Le calcul des efforts normaux et tangents est important pour la modélisation dynamique du système véhicule-voie en ferroviaire. Pour déterminer les forces tangentielles au contact roue-rail, les coefficients de Kalker sont utilisés dans la plupart des codes de dynamique ferroviaire, pour les différents modèles de contact. Ces coefficients ont été mesurés sur banc à plusieurs reprises dans les années 80. Une synthèse de ces travaux, réalisée par Hobbs, montre que certaines de ces mesures présentent une baisse pouvant atteindre 50% par rapport à la théorie de Kalker. L’objet de cette thèse est d’identifier d’abord les véritables causes de la dispersion constatée entre les différentes mesures, généralement attribuée à la contamination de la su...
