摘要
随着声呐技术的迅速发展,水声通信在海洋科学研究及海洋开发中发挥着非常重要的作用,水声通信换能器是水声通信设备中负责电声转换的重要部件。研究了一款带底座的溢流圆管换能器,通过有限元仿真计算了换能器发送电压响应和方向性等参数,优化了换能器中的陶瓷元件和底座的结构尺寸,制作并测量得到一款半空间指向性的水声通信换能器,换能器的工作频段为11~23 k Hz,带内起伏为3 d B,最大发送电压响应为133 d B,-3 d B垂直开角大于180°。
With the quick development of sonar technology, underwater acoustic communication plays an important role in marine scientific research and ocean development. Underwater acoustic communication transducer is the important part of the electric sound conversion system for acoustic communication. This paper studies a kind of underwater acoustic communication transducer using free-flooded ring typed tube. The ceramic components and shell structure of the transducer are optimized by the finite element simulation. A half-space directional underwater acoustic communication transducer is made and measured with the specifications as follows： 11~23 k Hz working band with 3 d B fluctuation, 133 d B maximum transmitting voltage response and the-3 d B vertical angle of greater than 180 degrees.
