Flexural vibration of piezoelectric ceramic rectangular thin plate

An analytic method is presented to study the flexural vibration of the piezoelectric ceramic rectangular thin plate. Under the boundary conditions of free edges and simply supported edges, the resonance frequency equations are derived, and the relation between the vibrational modes and the geometrical dimensions are analyzed. Theoretical analyses show that the flexural vibration of the slender piezoelectric ceramic slip and the stripe mode flexural vibration of the thin ractangular plate are the limiting vibration modes of the plate. Experimental results show that the calculated resonance frequencies are in good agreement with the measured results.
