Abstract
A vibration damping mechanism (90) for damping vibrations to prevent coupling of vibration modes of the carrier structure (106) with vibration modes of a rotor (100) secured to the carrier structure (106). The mechanism comprises a support (3) suitable for being fastened to the rotor (100) and at least one resonator (1) including a mass (5) carried by the support (3) via mobile mounts (6) for mounting the mass (5) to move on the support (3), the mechanism (90) including at least one damper (8) for damping the resonator (1), with the damper being interposed between the resonator (1) and an engagement member (9) on the support (3).
