Analysis of composite plates with piezoelectric actuators for vibration control using layerwise displacement theory

摘要: In order to evaluate closed loop performances of the composite plates with distributed piezoelectric actuators, it is essential obtain more exact system parameters such as natural modes, damping ratios, and modal actuation forces. this paper a refined analysis actuators for vibration control has been performed. The in-plane displacements through thickness have modeled using layerwise theory. This model can describe strain distributions capability realistic modeling boundary conditions. finite element method based on developed mechanics formulated. constitutive equations materials used determine forces, energy applied analyze capacity structures. Through comparison present results those available, accuracy was verified. evaluated simple algorithms. shear deformation plate theory, concluded that smart actuators.
