Transient Analysis of Transducer Arrays

Abstract

A method for analyzing the transient behaviour of the transducer velocities in an array of transducers is described and used to obtain results for several typical situations. The method is based on a finite difference iteration solution of the differential equations for the array. It uses results of Mangulis for the transient self acoustic loading and makes approximations for the acoustic interactions based on Rayleigh's general expression for the field of a source in an infinite, rigid plane. The results obtained are for small plane arrays of small circular pistons. They show that the transient period can be considerably extended by the interactions and that effects of practical importance such as velocity overshoots often occur during the transient period.
