【Abstract】 This paper considers the modeling of the ship water chamber subsystem in ship lift. Periodic response of the system to harmonic oscillation is studied. By the assumption of potential flow and mini amplitude oscillation, perturbation methods are employed to linerize the hydrodynamic problem. Now that ship and ship reception chamber are slender bodies, strip method is developed for conversion of three dimension problems into two dimensional ones. The finite element method is used to solve the equations. Using the program will lead to obtaining important parameters: added masses, amplitude of every type of motion and resonance frequency.更多还原
