Broadband transducer with tube-beam coupling structure

  • 摘要: 对一种管梁耦合宽带换能器进行了研究,通过在圆环换能器中加入弯曲梁组成管梁耦合结构,增加有效工作模态,利用多模谐振耦合优化设计,可使换能器的工作带宽向低频大幅扩展.理论计算与实测结果均表明,管梁耦合换能器具备频带宽、功率大、尺寸小、深水性能好等特点,兼具圆环换能器与弯张换能器的优势,工作性能优良,设计灵活多变.
    Abstract: A broadband transducer with tube-beam coupling structure is presented. Flexural beams are put into a traditional segmented ring transducer including inactive portions to form a new tube-beam coupling structure with more useful working modes. Using multiple-mode-coupling design technique, the bandwidth of transducer could be expanded efficiently towards low frequency range. The optimization study of the electroacoustic parameters is carried out by finite element analysis at first. Then a prototype is manufactured and measured. It is shown that this projector combines the fine qualities of flextensional transducer with those of ring transducer by both the simulated and experimental results. It could achieve low frequency, high power and wide band performance from compact size. In addition, it is suitable for deep submergence operation when using flee-flooded design.
