Description

Description Soundac damping cassettes have been developed for the purpose of reducing the amplitude of free resonant bending waves which are set up in response to vibrations in steel or aluminium plating and constructions. The damping cassettes are suited on applications where the sheet-thickness exceeds 5 mm. The cassettes can easily be welded to the construction in contrast with conventional methods of damping with a constraining layer. The cassettes are designed to damp the resonance of first and second order bending waves on the treated construction, by means of constraining the panel motion. The reduction is effective across a broad frequency range, as a result of the damping material which is used in the cassettes. Treatment with the damping cassettes provides energy absorption even at the higher frequencies which can be born in the construction. The principle The cassettes are composed of a 1 meter long U-profile in which the viscoelastic material is cast. In this material are the 10 to 20 individual legs imbedded. These legs are welded to the structure. As the structure is subjected to vibrations the every of the motion is transmitted through the legs of the cassette which is resisted by the damping effect applied by the cast viscoelastic material. When the cassettes are applied to the structure there should be 2 cassettes per square meter with a distance of approx. 400 mm.
