In this paper, we present a method for the determination of the elasticity modulus in the vibratory domain of materials. This approach is based on research and interpretation of the spectrum of natural frequencies resulting from natural vibrations ba

Vibration analysis aims at identifying potential failures of a rotating machinery from the monitoring of its vibration levels, i.e., by measuring the vibrations and comparing them to known failure vibration signals. For the diagnostic of gearboxes, n

Méthode d'identification d'un impact appliqué sur une structure admettant des modes de vibration basse fréquence faiblement amortis et bien séparés

Autor: Goutaudier, Dimitri

La détection d'impacts est une préoccupation majeure pour suivre l'intégrité d'une structure évoluant dans un environnement comportant des risques de collision. Ce travail consiste à développer une méthode d’identification d'impact applicab
