摘要
溢流环换能器是一种低频、宽带、大功率水声换能器,一般存在两种谐振方式,即液腔谐振和径向谐振。对溢流环换能器的两种谐振作了理论分析,并用有限元法建立模型进行计算,制作了换能器样品,并通过试验作了对比。结果表明,有限元法对于完善溢流环换能器的设计理论具有一定的指导意义。
Free-flooded ring transducer is a low frequency, broadband, high-power underwater acoustic transducer, and has cavity resonance and radial resonance. The paper analyses the theory of two resonances about free-flooded ring transducer, computes the model based on finite element method, and makes the sample of transducer. The result of contrastive experiment shows that the finite element method is significant in the field of modifying the designing theory of Free-flooded ring transducer.
