| 摘要: |
| 针对目前深海无人移动平台缺乏与其工作深度相匹配的复合同振式矢量水听器的问题,采用薄壁铝合金球壳作为矢量通道,压电陶瓷圆环作为声压通道,设计制作了一型大深度复合同振式矢量水听器,并用理论计算、有限元仿真和实验测试的方法对其声学性能和耐压性能进行了验证。该水听器的外径为85 mm,质量为398 g,平均密度为1 240 kg/m3,工作频段为20~3 000 Hz,矢量通道呈余弦指向性,灵敏度为-187 dB@500 Hz,声压通道无指向性,灵敏度为-191 dB@500 Hz,耐压深度为2 000 m。海上试验表明,该水听器能够搭载在水下滑翔机等深海无人平台上执行声学探测任务,在大深度声学探测领域具有重大的应用价值。 |

| Abstract: |
| In order to solve the problem that deep-sea unmanned mobile platforms lack combined vector hydrophones which match their working depth, a large depth combined co-vibrating vector hydrophone was designed and developed with the thin aluminum alloy spherical shell as its vector channel and the piezoelectric ceramic ring as its sound pressure channel. The acoustic performance and pressure resistance of the hydrophone was verified by theoretical calculation, finite element simulation and experimental test. The size of the hydrophone is Φ85 mm, with the mass being 398 g, and the average density being 1 240 kg/m3. Its working frequency range is from 20 to 3 000 Hz. The vector channel of the hydrophone is cosine directional, and its sensitivity is -187 dB@ 500 Hz. The sound pressure channel has non-direction, with the sensitivity being -191 dB @ 500 Hz. This vector hydrophone has a working depth of 2 000 m. Sea tests show that this hydrophone can be applied on deep-sea unmanned platforms, such as underwater gliders, and can carry out acoustic detection missions,which means that it has great application values in the field of deep-sea acoustic detection. |
