The presence of a substructure in a submerged cylindrical shell gives rise to dynamic interactions which influence the radiated acoustic field. The lowest modes of the substructure may resonate vigorously with a higher order mode of the shell. In this paper, a Lagrange's equations formulation is used to analyze the forced harmonic response of a submerged shell/substructure system. An infinitely long cylindrical shell is considered and the substructure is a plate with various types of connections to the shell. Harmonic forcing is applied to the structure and expressions are developed for the far-field radiated pressure. The frequency window method is used to simplify the analysis and to provide approximate solutions in a frequency range of interest.
