An active vibration control device for controlling vibration in a cantilevered member (12) and a method for the same are disclosed. The device is comprised of a cantilevered member (12) having a longitudinal axis (13) comprising a sensor (92) mounted near the free end of the member (12) to measure motion of the member (12) in a transverse direction and to produce a corresponding signal. A force generating assembly (64) is mounted to the member (12) near the free end to oppose the measured motion with a force thereby minimizing subsequent motion along the transverse axis caused by vibration.
Dispositif actif de réduction des vibrations permettant de réduire les vibrations d'un élément monté en porte-à-faux (12) et méthode correspondante. Le dispositif comprend un élément monté en porte-à-faux (12) d'axe longitudinal (13) équipé d'un capteur (92) monté près de l'extrémité libre du membre (12) et destiné à mesurer les mouvements de l'élément (12) dans une direction transversale et à produire un signal correspondant. Un moyen produisant une force (64) est monté sur l'élément (12) près de son extrémité libre afin qu'il oppose une force au mouvement mesuré pour minimiser le mouvement provoqué par les vibrations sur l'axe transversal.
