本文研究了圆柱形管道中薄圆盘与声介质相互作用的自由振动问题。基于经典理论和Galerkin方法，采用解析-数值方法研究了结构-声耦合效应。讨论了耦合效应，并将分析获得的结果与实验和有限元分析获得的相应值进行了比较。三组结果之间有很好的一致性。
Abstract This paper describes the free vibration analysis of a thin disc vibrating and interacting with an acoustic medium contained in a cylindrical duct. The effects of structural-acoustic coupling are studied by means of an analytical-numerical method that is based upon classical theory and the Galerkin method. The coupling effects are discussed, and results obtained from the analysis are compared with corresponding values obtained both experimentally and from a finite element analysis. There is good agreement between the three sets of results.
