摘要: This paper deals with the vibration analysis of a circular plate surface bonded by two piezoelectric layers, based on Kirchhoff model. The form electric potential field in layer is assumed such that Maxwell static electricity equation satisfied. validation theoretical model done comparing resonant frequencies coupled obtained and those finite-element analysis. mode shape from free generally shown to be non-uniform radial direction contrast what commonly assumed. have an effect host structure. proposed for provides means obtain distribution layer. design reference material application, as ultrasonic motor.
