Research on Analytical Method for Vibro-acoustic Response Analysis of Bi-directionally Orthogonal Stiffened Plates
摘要
Abstract
The analytical method for sound and vibration analysis of bi-directionally orthogonal stiffened plates is proposed. By using displacement and force continuity conditions between plates and stiffeners, vibration equations of the stiffened plate system are established. With the displacement function expressed as a two-dimensional Fourier series, one can convert the differential equations of the stiffened plates into linear algebraic equations. Thus, the solutions of free vibration and forced vibration of the stiffened plates can be obtained. Results of the present method demonstrate a good agreement with published results and the results of typical finite element analysis. Subsequently, the effect of stiffeners position on vibro-acoustic response of multi-stiffened plates is studied.关键词
