Abstract
This paper deals with the vibration characteristics of stacked transducers composed of piezoelectric discs, which are main elements of ultrasonic sensors or actuators. The stacked transducers were devised in the sense of natural frequencies. Two- or three-layer transducers were fabricated with piezoelectric discs of different diameters. The natural frequencies were determined by the finite element analysis and they were verified by comparing them with experimental results. It appeared that the natural frequencies of the stacked piezoelectric transducers include the natural frequencies of the constituent piezoelectric discs and the natural frequencies caused by stacking. Based on these results, it would be possible to predict the vibration characteristics of the stacked piezoelectric transducers in a design process.
