摘要
The work-energy relation of active constrained layer is studied through a variational aPproach, and is extended for the control of sound radiated from vibrating structure.Theoretical analysis indicates that, the power done by external force to structure can be regarded as two parts: one is completely dissipated by active and passive dampings; the other is dissipated in the form of sound. The results provide a new approach for active structural acoustic control.
