METHOD AND APPARATUS FOR REDUCING STRUCTURAL VIBRATION AND NOISE

摘要

A conjugate damper (100) for a structural panel (50) includes a constraining sheet (102) extending between a first edge (104) and a second edge (106). Each of the first edge (104) and the second edge (106) is at least partially coupled to a first surface (52) of the structural panel (50). The conjugate damper also includes a damping layer (120) coupled between the constraining sheet (102) and the first surface (52) such that, when the structural panel (50) is in a compressively deformed state, a thickness of the damping layer (120) in a direction generally normal to the first surface (52) is decreased relative to a baseline state. The damping layer (120) includes a viscoelastic material.
