摘要
本文给出一种有限元——亥姆霍茨积分方程结合法,计算有限长圆柱形水声换能器的电声特性。通过对一例换能器空气中及水中的电声特性的计算并与实测值比较,证明这种方法是很有效的。
A finite element-Helmholtz integral hybrid method has been developed to calculate the electro-acoustic performances of a finite length cylindrical transducer immersed in water. A numerical study concerned with electrical impedance and beam patterns of the transducer is presented. Experimental data are shown to support the numerical study.
