Acoustic suppression arrangement for a component undergoing induced vibration

The present invention relates to suppression of audible noises generated by mechanical components and, in particular, to suppression of noises generated by automotive vehicle engine components that are fabricated from metal or polymeric materials. An acoustic suppression arrangement for a component undergoing induced vibration is provided. The arrangement includes a component body having an interior surface and an exterior surface having a panel portion . A containment plate is provided having a spaced relationship from the panel portion. A first projector is connected to the component body panel portion and extends toward the containment plate . A second projector is connected to the containment plate. A connector system is provided to connect the containment plate to the component body while placing the first and second projectors in an interference fit. Vibratory energy of the component body is dissipated by frictional contact between the projectors
