  1. The calculated drafts covers the whole possible ship draft in the large amplitude motion ; secondly, the research creates and solves the ship large amplitude motion equations. on the one hand, the actual calculation takes into account the coupling between the different motion modes, on the other hand, in the process of calculation of the ship hydrodynamic coefficient, it considers the influence of the nonlinear factor. the hydrodynamic coefficient used in the calculation of froude - krylov force, diffraction force and radiation force changes instantaneously following the draft, and the hydrostatic buoyancy is computed very accurately for the instantaneous immerse hull

    本文的研究分為二個部分：首先利用frank源匯法計算水動力系數，計算包括不同吃水時的附加質量和阻尼系數，吃水范圍涵蓋了船舶大幅度運動時所有可能的吃水；然後建立和求解船舶大幅度運動方程，在實際計算時一方面考慮了運動模態之間的耦合，另一方面在計算水動力時，考慮了非線性因素的影響。 froude - krylov力、輻射力、繞射力中的水動力系數隨吃水瞬時變化，靜浮力的計算精確到船體瞬時濕表面積，最後用四階龍格?庫塔方法在時域內求解船舶運動方程，並進行了載荷計算。
