摘　　要：文章基于有限元(FEM)或有限元结合边界元(FEM/BEM)分析方法,对浸水结构振动及声辐射特性国内公开发表的文献进行梳理,从低频流固耦合的振动特性、弱耦合与强耦合的声辐射特性、直/间接边界元的非唯一性与奇异性等着重流体数值模拟方面,对国内相关研究进行了综述分析,就浸水结构振动及声辐射特性的研究发展动态做出了总结,为相关科研人员研究浸水结构振动特性及声辐射提供了有益参考。This paper summarizes the papers about the submerged structure vibration and acoustic radia-tion characteristics based on FEM or FEM/BEM published in China, emphasizes the numerical simulation on fluid, reviews and analyses the domestic research about the vibration characteristics of fluid-structure cou-pling, the acoustic radiation of weak and strong coupling and the non-uniqueness and singularity problems of D-BEM and I-BEM, summarizes the research and the least development about the submerged structure vibration and acoustic radiation characteristics, and provides some reference to other researchers who study the submerged structure vibration and acoustic radiation characteristics.
