| 摘 要： | 对基于类1-3-2型压电复合材料的高频相控阵换能器进行了理论分析和实验研究.通过切割与填充去耦材料制作类1-3-2型压电复合材料,并对类1-3-2型压电复合材料的基元进行布阵,在二维方向上形成4个子阵.通过对子阵适当相移,抑制主瓣和保留栅瓣,在空间上形成所需的发射与接收波束.实现了通过一个多元平面阵列形成4个所需的指向性波束,测速时避免了声学补偿.与传统使用4个活塞型收发换能器形成指向性波束的方法相比,相控阵换能器的几何尺寸显著减小.研究结果表明,基于类1-3-2型压电复合材料高频水声相控阵换能器具有高发射响应,宽频带,波束一致性好,结构紧凑,制作工艺简单可靠等优点.

| Abstract: | The theoretical and experimental analyses of the phased-array transducer based on analogous 1-3-2 type piezocomposite material are done in this paper. By incising and filling the piezoelectric ceramic circular resonator with decoupling material, the analogous 1-3-2 type piezocomposite material is fabricated. The elements of the piezocomposite material are embattled in planar directions to form four wave beams. The transmitting and receiving wave beams are achieved by phase-shifted to restrain the main lobe and reserve the grating lobe. Four required beams are formed by a plane phased array, and no compensation for sound velocity is needed. The size of the array is decreased compared to using 4 piston mono-static transducers. The results show that this type of phase-array transducer has the advantages of better performance for transmitting and receiving sound wave, compact and steady structure,easy way of making elements and electrode. |
