Dynamic response and noise transmission of discretely stiffened composite panels
Abstract
The surface protection systems of aerospace and aircraft structures are often constructed from discretely stiffened composite panels. This paper presents an analytical study of the dynamic response and structure-borne sound transmission of these structures due to random loading conditions. A generalized transfer matrix procedure is developed to obtain the required dynamic response solution. Modal decomposition is used to predict the interior noise transmission. Numerical results are presented for acousto-structural applications.
