摘　　要：本文设计并制作了一种Terfenol—D球形换能器,使用有限元分析软件ANSYS对换能器的电声参数进行模拟计算,计算结果与实验结果符合很好。换能器水中谐振频率f=6.3kHz,Q-3dB=2.63,证明具有低频、宽带的特点。A type of Terfenol-D spherical transducer is designed and developed. Using FEM software ANSYS, a series of electro-acoustic characteristics of the transducer has been modeled and the computed results are in good agreement with the measurements. With a resonant frequency of 6.3KHz in water and Q factor (-3dB) of 2.63, it is proved to be a type of low-frequency and broadband transducer.
