Large-Amplitude Multimode Response of Clamped Rectangular Panels to Acoustic Excitation

Abstract

A mathematical formulation and the solution procedure for rectangular panels under broadband random acoustic excitation are presented. Large-amplitude effect and multiple modes are included in the formulation. The generalized mass matrix and the generalized linear stiffness matrix using 15 terms in the assumed panel deflection function are derived. Subroutine programs that generate the mass and linear stiffness matrices have been developed. Continuing research efforts are outlined.
