doi:10.3969/j.issn.1000-1093.2014.07.020

Abstract

Abstract: In order to decrease the reflection coefficient of underwater platform and promote its stealth performance, a method of covering a sound absorbing material on the platform is proposed. The transfer matrix method is used to calculate the reflection and transmission coefficients of composite structure in underwater platform in the case of oblique incidence of sound waves. The influences of the arranging sequence and parameters of sound absorbing materials on the acoustic characteristics of underwater platform are analyzed. The results show that the reflection coefficient of platform without sound absorbing material is close to 1 ; the constant reflection coefficient curve of the platform with sound absorbing material is a hyperbolic curve as the functions of incident angle and frequency, and its reflection coefficient obviously descreases at high frequency. This shows the frequency selectivity in the absorbing performance of platform, and the absorption wave band of platform transfers to lower frequencies by increasing the thickness of sound absorbing material. When the loss coefficient of material raises, the reflection coefficient of platform goes down. The experimental results coincides well with the theoretically calculated results.

Key words: acoustics, absorption material, underwater platform, transfer matrix, reflection coefficient
