摘要
Abstract
Acoustic characteristic, which mainly depends on bubble, is one of the most important characteristics of ship wake. In this paper, the active acoustic characteristic of single bubble in ship wake is analyzed, and an elastic sphere shell's active acoustic reflection / scattering characteristic model of single bubble is established. A finite element model of double bubble is also set up combining the acoustic characteristic of bubble in different radius and the distribution analysis of bubbles in ship wake. Finite element analysis method is used to analyze the displacement varying with frequency under cyclic loading condition, thus the bubbles' resonant frequencies are obtained. The distribution of double bubble field under incident active sound source is computed to obtain the active acoustic reflection / scattering characteristic of double bubble.关键词
