A flexibly-mounted active vibration absorber (AVA) which has a secondary controllable mass M3. If the passive resonance of mass M2 of the tuned absorber is insufficient to control the input vibration, a secondary mass M3 is vibrated at a frequency, amplitude and phase sufficient to make up the deficiency in mass M2. Many embodiments are described which depict variations on the first spring used for flexibly mounting the AVA, the actuators used to drive the AVA, and the attachment features for attaching to a vibrating member. Further, in another aspect, means for counterbalancing the moments produced by the AVA are described.
Amortisseur de vibrations actif (AVA), articulé, qui comprend une masse secondaire M¿3? réglable. Lorsque la résonance passive de la masse M¿2? de l'isolant accordé ne suffit pas à maîtriser la vibration d'entrée, on fait vibrer une masse secondaire M¿3? à une fréquence, amplitude et phase suffisantes por compenser l'insuffisance de la masse M¿2?. Plusieurs modes de réalisation sont décrits, qui présentent également des variations sur le premier ressort utilisé pour articuler l'AVA, les organes de commande pour entraîner l'AVA et les éléments de fixation pour le raccordement à un élément vibrant. En outre, le moyen de compenser les moments produits par l'AVA est présenté dans un autre mode de réalisation.
