Abstract

The cylindrical overlapping piezoelectric transducer is mainly composed of the three cylindrical piezoelectric ceramics, bracket, metal bolt, rubber, waterproof layer and output cable. The transducer model was established, separately in the air and water, with ANSYS to calculate the vibration frequency and conductance .The transmitting response and directivity in water were also calculated .The results showed that the overlapping structure effectively improved the sensitivity of the piezoelectric transducer.
