Abstract
A calibration procedure for suppression of plate vibrations by means of piezoelectric RL shunt damping is developed, in which the spill-over from non-resonant vibration modes is included by a quasi-dynamic modal correction, taking both flexibility and inertia effects from the residual modes into account. The procedure includes the 2D behaviour of a shunted piezoelectric patch, represented in a finite element model with Kirchhoff plate kinematics. The calibration based on the plate model is compared to previous results for beams, illustrating the 2D effect of the patch and the influence from transverse contraction by the Poisson’s ratio. Finally, the ability to reproduce the desired level of attainable damping for a plate structure is demonstrated.
