Abstract:
A new type of sandwiched transducer, which is based on the analogous 1-3-2 type piezocomposite material is designed and analyzed. The frequency characteristics of the analogous 1-3-2 piezocomposite material and the frequency equations of sandwiched transducer are investigated by one-dimensional longitudinal vibration theory. By incising the PZT piezoelectric ceramic circular resonator, the analogous 1-3-2 type piezocomposite material is fabricated. The sandwiched transducer is made by analogous 1-3-2 type piezocomposite material. It is shown that this type of sandwiched transducer gains pure mode and wide band in the working frequency range and has well-distributed displacement. It can be widely used in high power ultrasonic and underwater emitter.
