摘要：

Acoustics design plays an important place in the design of torpedo. The structure vibration and sound radiation have great influence to the effectiveness of torpedo. The characteristics of structure vibration and sound radiation from torpedo were studied, and schemes to control the vibration and radiated noise were found. A simplified model of torpedo was set up and the numerical simulation was carried out. The radiated noise was predicted using the statistical energy analysis method. Several conclusions were obtained in the exploration of the way to reduce the vibration and noise.
