摘　　要：基于有限元和边界元法预报了鱼雷辐射噪声,运用SYSNOISE软件计算了鱼雷辐射噪声级,并得到了鱼雷辐射噪声声压级云图,为解决鱼雷振动与噪声控制问题指明了方向。Radiation noise from torpedo is predicted based on finite element method（FEM）and boundary element method（BEM）.Level of radiation noise from torpedo is calculated by use of SYSNOISE,and then cloud charts of sound pressure less（SPL）of radiation noise from torpedo are given,which shows the direction for overcoming the question of vibration and noise-reduction control of torpedo.
