碩士 === 國立成功大學 === 造船工程學系 === 85 === This paper calculationthe hydrodynamics problems for ship with forwordspeed in open sea, expecially on diffraction problem.This subject separtssteady problem in calm water ,and the unsteady problem where incident wavesact upon the ship ,bescide coupling effect must be consider. A translation source distribution has been developed to calculation steady problem,where the neumerical model adduce Hess & Smith''s method,and Shen & Farell'' s complex integration,additionally pulsating source distribution adopts Noblesse''s series expansion for unsteady problem. Panel method has been adduce to discret integral equations, and determine by matrix solution.Ship wave exciting forces and moments for series 60 (Cb=0.6, Cb=0.7) and WIGLEY models have been computed and compared to experiments data and strip theory results, good agree with this present method. So, this mathematics scheme can be a good bases for seakeeping ambit.
