摘要
通用宽带换能器(含低频到高频)一般是将不同类型的换能器进行组合使用,单个换能器独立设计再组合成阵,其综合体积及质量均大,且安装后其性能指标受影响(如换能器开角变小等)。该文在分析当前国内外宽带换能器研究现状基础上,结合小型遥控无人潜水器(ROV)搭载探测需求,提出具体设计指标要求。将复合棒换能器与数个压电陶瓷圆环进行开放式一体化组合设计,在满足小型ROV安装要求的基础上,实现了发射3~100 kHz、接收1~100 kHz的超宽频带覆盖范围,且开角不小于70°。水池及湖上实航实验结果表明,研制的换能器与仿真设计相符,实航测量结果与国内外相关结论一致性较好,具有广泛的工程实用价值。
The general-purposed wideband transducers(including low-frequency to high-frequency)are generally used in combination with different types of transducers.A single transducer is independently designed and then combined into an array.Its size is large and itsweight is heavy,and its performance specifications are affected after installation,such as the opening angle of the transducer becomes smaller.Based on the analysis of the current research status of broadband transducer at home and abroad,combined with the requirements of small remote operated vehicle(ROV)on the board detection,this paper puts forward the specific design requirementsof the underwater acoustic transducer.The composite rod transducer and several piezoelectric ceramic rings are designed in an open and integrated way.On the basis of meeting the installation requirements of small ROV,the ultra-widefrequency band coverage of 3~100 kHz for transmittingand 1~100 kHz for receiving is realized,and the opening angle is not less than 70°.The actual aviation test on the pool and the lake proves that the developed transducer is in line with the simulation design,the actual measurement results are in good agreement with relevant domestic and foreign conclusions,and have extensive engineering practical value.
