The vibration and the coupled interior sound field of a plate-ended cylindrical shell are studied in his paper. An analytic formulation considering the full coupling between the whole systems (shell, plate and acoustic cavity) is developed. The natural frequencies of the coupled system are obtained. The numerical solutions are then got using Broyden order 1 algorithm and modes superposition method. In this paper, not only the bending vibration of the plate is considered but also the in-plane vibrations of the plate, which is more close to the reality. Based on the previous structural-acoustic coupling model, exterior sound radiation pressure is calculated.
