Vibroacoustic modeling of elastic plates excited by turbulent boundary layer

A modeling method for studying the vibro-acoustic characteristics of rectangular plates with general boundary conditions excited by turbulent boundary layer (TBL) is developed in this paper. The Rayleigh - Ritz method, the classical theory of elastic plates and modified Fourier spectral approach (MFSA) are employed to establish the calculation model of the vibro-acoustic model of rectangular plates. In addition, the description of the pressure field is based on the cross-spectral density expression of Corcos models of the turbulent boundary layer. Then, considering fluid-structure interaction with the frequency response functions, the power spectral density of vibro-acoustic characteristics of plate with arbitrary boundary conditions can be calculated. The results indicate that, the results by the present method are consistent with those in the references, which validate the accuracy of the developed model.
