摘要: 多谐振宽带复合棒换能器因采取耦合多个振动模态的方式, 在拓宽频带方面取得了很好的效果而被广泛使用。为进一步适应水声信号技术的发展要求, 文中采用等效电路法和有限元分析法对前盖板弯曲振动的双激励源多谐振换能器性能进行了对比分析, 2种方法所得结论吻合较好。最后采用ANSYS有限元分析软件对三激励源多谐振换能器进行了研究。结果表明, 双激励多谐振换能器的带宽得到有效拓宽, 三激励源多谐振换能器在工作频带内受质量块厚度的影响较小。文中工作可为多谐振宽带换能器带宽和起伏的设计提供参考。Abstract: Multi-resonant broadband Tonpilz transducer takes the way of coupling multiple vibration modes, so it broadens frequency band. In this paper, for the development of underwater acoustic signal technology, the equivalent circuit method and the finite element analysis method are used to analyze the performance of the double-excitation source multi-resonant transducer for bending vibration of the front cover plate. The results of these two methods are in good agreement. Moreover, the finite element analysis software ANSYS is employed to investigate triple-excitation source multi-resonant transducer. The results show that the frequency band of the double-excitation source multi-resonant transducer is effectively broadened, and the triple-excitation source multi-resonant transducer undergoes small influence of the mass thickness in its working frequency band. This study may provide reference for design of bandwidth and fluctuation of the multi-resonant broadband transducer.
