Department of Weaponry Engineering, Naval University of Engineering, Wuhan 430033,China

摘要

摘要: 将金属与压电陶瓷物理复合的钹式换能器体积小、重量轻，适合于开发低频换能器。研究了低频换能器的设计问题，利用有限元方法分析了介质变化对钹式换能器导纳和频率特性的影响，并与Langevin压电换能器的性能进行了比较，给出了钹式换能器性能随压电陶瓷物理与结构以及金属帽结构参数的变化规律；给出了低频钹式换能器的产品设计实例。研究结果对于优化钹式换能器以及开发水下低频换能器技术有应用价值，也为后续的制作工艺与相关的水池实验研究提供了技术支持。

Abstract: Cymbal transducer composed of metal and piezoelectric ceramic has the advantage of small volume, which is significant in development of low frequency transducer. The effects of media on admittance and resonance frequency of cymbal transducer are analyzed with the finite element analysis, the performances of cymbal and Langevin transducers are compared, and the property variation of cymbal transducer with the physical parameters of the ceramic and the structural parameters of the metal cap is determined. Moreover, a prototype of cymbal transducer with low frequency is designed. This study may be helpful for optimizing cymbal transducer and developing low frequency transducer in underwater applications, and may provide technical support to fabrication technique and tank experiment.
