摘要
为了提高现代鱼雷的作战性能,适应复杂环境,研制了宽带自导系统,旨在提高声纳基阵的整体性能。本文采用了有限元分析方法,借助ANSYS软件设计了匹配层水声宽带换能器,通过调整匹配层的声速、密度及厚度,分析了该类换能器的性能,包括换能器谐振频率、发送电压响应、自由场电压接收灵敏度以及收发频带宽度等,并对其结构进行了优化。研制了匹配层水声宽带换能器并进行了水池试验,对比分析了理论设计与试验结果,其测试结果与计算结果具有较好的一致性。本文研究可为声纳基阵设计提供借鉴。
A broadband transducer with matching layer was designed with finite element method （ FEM ） and ANSYS software to make modern torpedo adapt complicated environment. The acoustic velocity, density and thickness of the matching layer were adjusted to analyze the acoustic characteristics of the transducer, including syntonic frequency, transmitting voltage response, receiving sensitivity of free field voltage, and receiving transmitting frequency bandwidth, and to optimize its structure, Tank test of the transducer was conducted, and the results agreed well with computation. This study may offer a referonce for sonar array design.
