Title
(EN) VIBRATING-TRAP DEVICE WITH DISTRIBUTED RESONATORS
(FR) DISPOSITIF DE PIÈGE VIBRATOIRE A RÉSONATEURS DISTRIBUES
Abstract
(EN)
The invention relates to a vibrating-trap device (1) intended to be attached to a rotating structure subjected to vibrations, said device being mounted on a rotary shaft (2) of the structure and comprising multiple vibrating resonators (3) to trap the vibrations, said resonators being spatially adjacent to one another by being connected to the structure, each resonator (3) having the shape of a blade having a free end and a rigidly attached end, the width of this blade being aligned with the rotary shaft, each resonator (3) having natural vibration frequencies. The invention is characterized in that each resonator (3) is made of metal, the device (1) having an at least partial star shape with each resonator (3) forming an arm of the star, the free end being furthest from the rotary shaft (2), the spatial distribution of the bodies of the device (1) achieving the inertial equilibrium thereof relative to the rotary shaft (2).

Dispositif (1) de piège vibratoire destiné à venir se fixer sur une structure tournante sujette à des vibrations, monté sur un axe (2) de rotation de la structure et comprenant plusieurs résonateurs (3) vibratoires pour le piégeage des vibrations, voisins spatialement les uns des autres en étant liés à la structure, chaque résonateur (3) présentant la forme d'une lame avec une extrémité libre et une extrémité fixée rigidement, la largeur de cette lame étant alignée avec l'axe de rotation, chaque résonateur (3) présentant des fréquences propres de vibration, caractérisé en ce que chaque résonateur (3) est réalisé en un matériau métallique, le dispositif (1) présentant au moins partiellement une forme d'étoile avec chaque résonateur (3) formant une branche de l'étoile, l'extrémité libre étant plus éloignée de l'axe (2) de rotation, la distribution spatiale des masses du dispositif (1) satisfaisant à son équilibrage inertiel relativement à l'axe (2) de rotation.
