摘要

摘要为了提高高频水下换能器的波束宽度，设计制作了基于1-3压电复合材料的椭球帽和球帽换能器。采用有限元仿真分析了换能器的发射电压响应水平和波束方向性曲线。该换能器由弯曲1-3压电复合材料制成。与球帽换能器相比，椭圆球帽换能器具有开束角宽、指向性曲线相对光滑的优点。仿真和实验结果表明，复合换能器在水下环境中具有较大的覆盖面积。

High-frequency wide beam underwater transducer based on 1–3 piezocomposite

Abstract In order to increase the beam width of high-frequency underwater transducer, ellipsoidal cap and spherical cap transducer based on 1–3 piezocomposite were designed and fabricated. Finite element simulation was used to analyze transmitting voltage response level and beam directivity curve of the transducer. The transducer was fabricated by the curved 1–3 piezoelectric composite. Compared with spherical cap transducer, the elliptical spherical cap transducer has the advantage of wide beam opening angle and relatively smooth directivity curve. Both simulation and experiment results showed the potential of a broad covered area of the composite transducer in underwater environment.
