Abstract

Active Constrained Layer Damping (ACLD) treatments with active piezoelectric materials and passive Visco-Elastic Materials (VEMs) combine the advantages of both conventional Active Damping (AD) and Passive Constrained Layer Damping (PCLD) treatments. A beam Finite Element (FE) model has been developed for the beam partially covered with ACLD treatments on both sides of beam. For modeling the frequency dependent damping behavior of the VEM, the Golla-Hughes-McTavish (GHM) model has been used. In all, four systems have been studied viz., bare beam, beam-piezo (AD), beam-VEM (PCLD), and beam-VEM-piezo (ACLD). A set of experiments has been conducted on all the systems. A very good match between theoretical and experimental predictions, in terms of free vibration response as well as closed loop feedback controlled dynamic response, has been established.
