摘要： 针对水下声学滑翔机样机研制对小尺寸、耐压复合同振式矢量水听器的迫切需求，设计面向水下滑翔机平台的耐压复合同振式矢量水听器。根据矢量水听器工作原理，对其声压通道和矢量通道进行声学设计；仿真分析压电陶瓷元件和薄壁铝合金壳体耐压特性，完成矢量水听器整体结构设计与制作；进行矢量水听器耐压能力及电声参数测试，将该水听器集成应用于水下声学滑翔机。在南海某海域开展海上试验，采集100~3 000 Hz范围内水下声场信息，给出不同频点噪声级随时间的变化曲线，且得到了水面航船经过时不同频点的噪声级变化。结果表明，矢量水听器在1 200 m深处可靠工作，设计的矢量水听器满足水下声学滑翔机样机研制应用需求。

Abstract: A combined pressure-resistant co-vibrating vector hydrophone for underwater glider platform was designed to meet the needs of developing a combined small size and pressure-resistant co-vibrating vector hydrophone for underwater glider prototype. The sound pressure and vector channels are designed acoustically according to the working principle of vector hydrophone. The pressure-resistant characteristics of piezoelectric ceramic elements and thin-walled aluminum alloy shell are simulated and analyzed. The pressure-resistant capacity and electro-acoustic parameters of the vector hydrophone were tested, and the vector hydrophone was integrated into the underwater acoustic glider. Sea trial was carried out in a sea area in the South China Sea. The information of underwater acoustic field in the range of 100- 3 000 Hz was collected during the sea trial, the changing curves of different frequency noise levels with time were given, and the change of nose level at different frequency points was got when a surface ship passed. Results show that the vector hydrophone can reliably work in the depths of 1 200 meters and the different frequency noise level changes, the design of the vector hydrophone can meet the demand of application of underwater acoustic glider prototype.
