Abstract

L'invention concerne un procédé de serrage d'attaches de rails de la superstructure de voies de chemin de fer, qui fait intervenir des machines ou unités de vissage mobiles monobroche ou multibroches. Celles-ci sont généralement entraînées par des moyens électriques, pneumatiques ou hydrauliques. L'invention a pour objectif de développer un procédé qui permette le montage de brides élastiques dans leur position cible au moyen d'un dispositif de vissage de manière contrôlée et fiable de façon à éviter la formation de fissures dans les traverses, un processus de vissage à la vitesse la plus élevée possible, une adaptation automatique à différents états des liaisons par vis et à différents types de fixation ainsi qu'une documentation exacte des états. A cet effet, on détermine que la position cible de la boucle centrale d'une bride élastique (Skl) a été atteinte pendant ou à la fin du vissage directement ou indirectement par une mesure de distance appropriée et/ou un calcul approprié du profil des paramètres de la commande de machine.
