Abstract
A new method and device for actively-controlled constrained layer (ACLD) treatment which can be used as an effective means for damping out vibrations and sounds from flexible structures are described. The ACLD treatment consists of a visco-elastic damping layer which is sandwiched between two piezo-electric layers. The three-layer composite ACLD, when bonded to a surface which is subject to vibrational and/or sound disturbances, acts as a smart constraining layer damping treatment with built-in sensing and actuation capabilities. The sensing capability is provided by the piezo-electric layer bonded to the surface of the flexible structure, whereas the actuation or control capability is generated by the other piezo-electric layer which acts as an active constraining layer.
