Abstract :
In the surrounding of water, the harmonic response of Cymbal transducer based on 1-3 piezocomposite was analyzed with finite element analysis method in this paper. 1-3 piezocomposite was used as piezoelectric phase instead of piezoelectric ceramic and the brass foil was used as end cap electrode of the Cymbal transducer. The mathematic model of this new type of piezocomposite transducer was established. Three-dimensional models of Cymbal transducer based on 1-3 piezocomposite were developed in the modeling. With ANSYS software and boundary elements, the admittance, sending voltage response and free-field voltage receiving sensitivity of this new piezocomposite structure were taken into account, and the curves between admittance, sending voltage response and free-field voltage receiving sensitivity and frequency were investigated. Fabricate the samples of Cymbal transducers of this new type structure. Test the admittance, sending voltage response and free-field voltage receiving sensitivity of the transducers in the partially anechoic pool of factory 6971. The results show that the resonance frequency of the transducer is about 21 kHz, and its work band as a receiving transducer is below 10 kHz. There is good agreement between modeling calculation results and measurement for the Cymbal transducers. So the Cymbal transducer is practical and feasible.
