Dynamic and acoustic response of coupled structure/dense fluid axisymmetric systems excited by a random wall pressure field

Abstract : A numerical method for predicting medium frequency random vibrations of coupled fluid-structure axisymmetric systems excited by random wall pressure field is described. The structure is inhomogeneous, viscoelastic and linear and occupies a bounded domain. The internal inhomogeneous fluid is compressible and occupies a bounded domain. The external homogeneous fluid is compressible and inviscid. The structure and the internal fluid are analyzed by the finite element method and the external fluid by an integral equation method. An applictaion is described, and the numerical predictions are compared with experimental results.
