The strength of piezoelectric transducer sat static loading and vibrations was investigated. The theoretical model of strength for piezoceramics stripe glued to structural element was developed. Using the concept of ‘weak chin’ and the results of stress state analysis of three-layers structure with the cracks in one of layers. The general tendencies of effect of this structure parameters were defined. The effect of mechanical loading of piezoceramics transducer to its stress state and destruction can be decreased by rational selection of its geometrical parameters and thickness of coupling layer.
