The submarine structure is simplified to single or double infinite cylindrical shell stiffened with rings, bulkheads and stringers, focusing on underwater sound radiation from the single shell. the shell motion is described by donnell ' s theory including excitation forces and reactions of rings, bulkheads, stringers and fluid, which leads to the fluid - structure coupling vibration equation. expressing displacements by velocities, applying modal expansion circumferentially and fourier transformation longitudinally result in the shell ' s modal equations of motion
殼體的運動方程採用較為簡單的donnell理論描述，運動方程中包括了激勵力、加筋結構（環肋、艙壁和縱骨）和流場對殼體的作用力，從而組成流場-結構的耦合振動方程，並進一步將方程中的位移用速度表示，然後沿軸線方向進行fourier變換，將速度和各項荷載沿圓周方向進行模態展開，得到了殼體振動的模態運動方程。 -
