An Equivalent-Circuit Model for Flexural-Disk Transducers

Abstract

The goal of this project was to develop a set of analysis tools for performance prediction of flexural-disk acoustic projectors. The emphasis is on analytically based formulations designed to merge the physics of the flexure-disk structure with typical operational requirements of frequency. source level, bandwidth, and operating depth. While finite element analysis coupled with acoustic radiation models would be used to refine designs. analytical models permit isolation of the major effects of essential design variables. By developing an understanding of the transducer performance. the effectiveness of various strategies for flexural-disk designs can be evaluated. The model described in this report covers both center-supported and edge-supported structures and two and three-layer configurations.
