摘要:
The invention concerns a method and device for filtering and damping vibrations between a first element (2) subjected to an incident vibratory wave and a second element radiating a filtered vibratory wave. Said device comprises a vibratory energy transfer interface consisting of an elastic component (1) and a dissipative component (7) attached in parallel to the elastic component, to ensure filtering and damping or the incident vibratory wave. The dissipative component (7) consists of two separate rigid frames (4, 5) for punctually or continuously deflecting, optionally, through a lever arm effect, amplifying the vibratory energies generated by the elastic components (1) towards a dissipative material (6) interposed between them, said dissipative component (7) providing a damping of the elastic component (1).

摘要:
A method for reducing the amplitude of vibration and the pressure wave (6) from a radiating surface (5) and/or an incident surface (3) of a material exposed to mechanical and/or acoustic vibration. The material consists of an anisotropically shaped heavy resilient structure with an internal geometry capable of deflecting and localizing vibration (7) within the structure. A specific material may be incorporated into the areas where vibrational energy is localized in order to convert the vibrational energy into another form of energy.
