摘　　要：结构振动和声学特性在水下潜器的声隐身中扮演非常重要的角色,其机理非常复杂,半个多世纪以来一直是持续研究的主题。本文首先介绍潜艇技术发展的趋势,作为其结构振动和声学问题的背景。然后回顾了五十多篇文献,并将其简明归纳为三个主题:无论结构是有限或者无限的,加筋、内部结构以及流体载荷对水下结构振动和声学问题的影响。本文所归纳的结论将为相关领域的研究提供简明但是有价值的参考。Structural vibration and acoustics characteristics play a very important role in the acoustic stealth for underwater vehicles,their mechanisms are quite complex and the subjects studied continuously for more than half a century.The submarine technique development trend is introduced firstly as the background for its structural vibration and acoustics.Then more than fifty papers are reviewed and categorized concisely into three subjects,i.e.,effects of stiffeness,internal components and fluid loading on vibration and acoustics of a submerged structure whose length is finite or infinite.The conclusions summarized here provide brief but useful references for the research in related areas.
