Abstract

L'invention concerne des rails sur lesquels des véhicules sur rails peuvent se déplacer. Pour réduire les bruits de roulement, une partie supérieure du rail (champignon de rail) est reliée élastiquement à la partie inférieure du rail (patin de rail). La liaison du champignon au patin se fait par un logement élastique. Pour obtenir une réduction de bruit, la masse décalée du champignon de rail (appelée masse pertinente) doit être faible en premier lieu, et en deuxième lieu, l'amortissement du logement élastique en cas de contrainte exercée par la roue, doit être bien plus doux que la raideur du contact roue/rail (appelé raideur de contact). Les conditions pour la réduction du bruit sont à l'origine de règles de construction et de modes de réalisation pour un rail insonorisé.
