Dynamic Modeling Of Piezoelectric Laminated Plates Using Finite Element Method
Abstract
Active control systems that rely on piezoelectric materials are effective in controlling vibrations of structural components. In the present work, a finite element model is developed to study the dynamic behavior of laminated composite plates with integrated sensors and actuators. The model is valid for both continuous and segmented piezoelectric elements that can be either surface banded or embedded in the laminated plate. The formulation is based on the shear deformation plate theory and is applicable for both thin and moderately thick plates. The charge generated by the sensor and the response of the plate to an actuator voltage can be computed independently. These features are then coupled with a constant-gain control algorithm to actively control the transient response of the plate in a closed loop. Finite element solutions are presented to demonstrate the influence of sensor location, actuator location, stacking sequence and boundary conditions on the dynamic behavior of laminated plates.
