Research output: Contribution to journalArticlepeer-review


In the paper, a hydrodynamic model including the characteristics of maneuvering and seakeeping is developed to simulate the six-degree freedom motions of submarine sailing near the sea surface. The corresponding wave exciting forces on the submarine moving in waves are calculated by the strip theory, which is based on the source distribution method. With the hydrodynamic coefficients relevant to the maneuvering and seakeeping, the fourth-order Runge-Kutta numerical method adopted to solve the equations of motions and six-degree of freedom of the motions for the submarine at shallow submergence can be obtained. The hydrodynamic numerical model developed here can be served as a valuable tool for analyzing depth controlling behaviors of the submarine near the sea surface.
