摘要：The vibration response of an infinite fluid-loaded plate, reinforced with two sets of orthogonal rib stiffeners, is investigated. The stiffeners are assumed to exert only forces on the plate. With the displace-ment continuity condition of the plate and the stiffeners, the vibration response of the rib-stiffened plate to a harmonic pressure in the wavenumber space is established by using the Green function and Fourier trans-forms. Applying the space harmonic method, the vibration displacement of the stiffened plate is then expressed as infinite sets of space harmonic amplitudes. After having a numerical solution for these amplitudes, the Fourier inverse transform is employed to find an expression for the vibration response of the stiffened plate in the physical space. Numerical results show that this method converges rapidly.
