| Abstract: | Structural noise radiation prediction is the base and premise of torpedo acoustic design.A statistical energy analysis（SEA） model of torpedo structure is established by using AutoSEA to predict structural noise radiation level of torpedo based on a arithmetic example.Case simulation results show that the SEA method is suitable for the analyses of structural vibration and sound radiation characteristics of torpedo,and can be used in engineering application. |
