Abstract:
1. A mechanism for damping vibrations to prevent coupling of vibration modes of the carrier structure with vibration modes of a rotor secured to said carrier structure, wherein the mechanism comprises: a support suitable for being fastened to said rotor; at least one resonator including a mass carried by said support in a pendular manner via mobile mounting means for mounting said mass to move on said support; and damper means for damping the resonator, said damper means being interposed between first and second adjacent engagement members, wherein said mobile mounting means comprise one hinged arm per mass, each hinged arm being arranged as a lever arm having a longitudinal axis, being hinged to the support and being hinged to the damper means through the first engagement member at one end and carrying the mass at another end, with a center of mass of the mass in line with the longitudinal axis in a plane of rotation.
