Research on Simulation and Optimization Design of Type Ⅶ Flexural-tension Transducer
Flexural-tension transducer is a typical low-frequency high-power transducer,among which the flexural-tension transducer Type Ⅶ has good pressure resistance because of its special concave elliptic cylinder structure,which can meet the needs of deep water work.In this paper,through COMSOL simulation and optimization design,a type Ⅶ bending tension transduc-er is obtained.Its size is 170 mm*100 mm*40 mm(long axis*short axis*height),its resonant frequency in water is 1.7 kHz,and the maximum transmission voltage response is 126 dB.It has the advantages of small size,low frequency and high power emission.When the transducer shell material is titanium alloy,its pressure can be up to 6 Mpa.And the structure of transducer is flat,which has the prospect of transducer array application.The total height of the transducer triad array is not more than 200 mm,the resonant frequency is 1.4 kHz,and the maximum sound source level is expected to reach 190 dB.
