Bending vibrations of rectangular piezoelectric drives of a bimorph structure in an alternating transverse electric field

The problem of interaction of an electric field with a rectangular plate of a bimorph structure widely used in modern vibration displacement mechanisms as actuators in bending vibration modes are considered. Based on the solution of the basic equation of the plate vibration and the selected harmonic excited electric field, taking into account the boundary conditions for fixing the bimorph plate, three problems are solved in which, the resonance vibration frequencies are determined. The mentioned tasks can have a practical application in the development, design and control of piezoelectric drives (piezo actuators) in vibration displacement mechanisms and for the liquid emulgation
