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；然后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，最后用四階龍格?庫塔方法在時域內求解船舶運動方程，并進行了載荷計算。 |
