ABSTRACT
The objective of this paper is to develop the modeling of adaptive composite structures for active vibration control. The first order shear deformation beam theory is used for the analysis to ensure accurate bending solutions. Experimental, theoretical and numerical modeling approaches are conducted into active vibration control of laminate beam structures with bonded and embedded piezoelectric actuators. The assumed-modes method can predict the natural frequencies and mode shape of the laminate beam accurately. The modeling of the dynamic response of composites structures is presented. Modal analysis is done for determining the natural frequencies and mode shapes of the structures. The results obtained by the assumed-modes method and the theoretical solutions are validated through the experimental results obtained from (5). Finally, the effects of the number and locations of the actuators on the control system are also investigated.
