Underwater Acoustic Transducer And Transducer Array Technology

The research of underwater transducer and transducer array is playing a decisive role in the development of modern marine military equipment. Based on the real situation of submarine and antisubmarine warfare(ASW), According to the classical design theory of transducer or transducer array, a sonar will be researched and made , which has the feature of more wider bandwidth, more lower operating frequency, more lager radiation acoustic power, more farther operating distance, more higher researching efficiency and more higher directive accuracy . This thesis will mainly introduce the design idea, mading procedure and empirical analysis about piezoelectric transducer and cylindrical transducer array. The full coverage include as following:1. The physical property of piezoelectric ceramic; performance reference and empirical principle about transducer and array.2. The operating principle and design method of radial polarization cylindrical piezoelectric hydrophone.3. The operating principle, design method, mading technology, empiricalanalysis of horn-type longitudinal tonpilz piezoelectric transducer. And . the software of transducer aided design for this type.4. The operating principle, design method, mading technology, empiricalanalysis of cylindrical transducer array.
