Title
(EN) ADAPTIVE TUNED VIBRATION ABSORBER
(FR) ABSORBEUR DE VIBRATIONS ACCORDÉ ADAPTATIF
Abstract
(EN)
A system may detect a vibration being applied to a tuned vibration absorber. The tuned vibration absorber may include a beam, a mass, springs, a sensor, and an actuator. The mass may be disposed on the beam at a current position. The actuator may be configured to adjust a position of the mass on the beam. The system may identify a target position of the mass on the beam based on the detected vibration. The system may generate a drive signal, based on the target position, to control the actuator to adjust the position of the mass on the beam. The system may control the actuator to adjust the position of the mass from the current position on the beam to the target position on the beam to attenuate the vibration.

L'invention concerne un système pouvant détecter une vibration appliquée à un absorbeur de vibrations accordé. L'absorbeur de vibrations accordé peut comprendre une poutre, une masse, des ressorts, un capteur et un actionneur. La masse peut être disposée sur le faisceau au niveau d'une position actuelle. L'actionneur peut être conçu pour ajuster une position de la masse sur la poutre. Le système peut identifier une position cible de la masse sur la poutre sur la base de la vibration détectée. Le système peut générer un signal d'entraînement, sur la base de la position cible, pour commander l'actionneur afin d'ajuster la position de la masse sur la poutre. Le système peut commander l'actionneur pour ajuster la position de la masse de la position actuelle sur la poutre à la position cible sur la poutre pour atténuer la vibration.
