【摘要】：對(duì)一種管梁耦合寬帶換能器進(jìn)行了研究,通過(guò)在圓環(huán)換能器中加入彎曲梁組成管梁耦合結(jié)構(gòu),增加有效工作模態(tài),利用多模諧振耦合優(yōu)化設(shè)計(jì),可使換能器的工作帶寬向低頻大幅擴(kuò)展.理論計(jì)算與實(shí)測(cè)結(jié)果均表明,管梁耦合換能器具備頻帶寬、功率大、尺寸小、深水性能好等特點(diǎn),兼具圓環(huán)換能器與彎張換能器的優(yōu)勢(shì),工作性能優(yōu)良,設(shè)計(jì)靈活多變.
[Abstract]:A kind of tubular beam coupling wideband transducer is studied in this paper. By adding the curved beam to the loop transducer to form the tubular beam coupling structure, the effective working mode is increased, and the multi-mode resonant coupling optimization design is used. The operating bandwidth of the transducer can be greatly expanded to low frequency. The theoretical calculation and the measured results show that the coupling transducer has the characteristics of high frequency bandwidth, large power, small size and good performance in deep water. It has the advantages of ring transducer and flexural transducer, excellent performance and flexible design.

【正文快照】： 引言圓環(huán)換能器是最常用的水聲換能器類型之一,具有結(jié)構(gòu)簡(jiǎn)單、性能穩(wěn)定、布陣方便等優(yōu)點(diǎn),其工作原理、結(jié)構(gòu)設(shè)計(jì)和工藝優(yōu)化等各方面研究均比較成熟。傳統(tǒng)圓環(huán)換能器一般使用壓電陶瓷元件的徑向振動(dòng)基頻模態(tài)進(jìn)行工作,需要大功率工作時(shí)通常設(shè)計(jì)成鑲拼結(jié)構(gòu),鑲拼單元可以全部由壓電，
