Abstract

La présente invention concerne un procédé et un système (100) pour effectuer une identification de vitesse et de défaut d’un composant tel que, par exemple, un palier. Le procédé peut être mis en œuvre par un ordinateur (120, 140), de telle façon que l’ordinateur reçoit des données de surveillance d’état de la part d’un ou de plusieurs capteur(s) (110). L’ordinateur balaye des motifs sur une plage de vitesses par rapport aux données de surveillance d’état et multiplie chaque composante de motif des motifs par une composante spectrale environnementale correspondante. L’ordinateur additionne ensuite les composantes de motif afin de produire un ou plusieurs résultat(s). Figure 1
