- 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(gè)部分：首先利用frank源匯法計(jì)算水動(dòng)力系數(shù)，計(jì)算包括不同吃水時(shí)的附加質(zhì)量和阻尼系數(shù)，吃水范圍涵蓋了船舶大幅度運(yùn)動(dòng)時(shí)所有可能的吃水；然后建立和求解船舶大幅度運(yùn)動(dòng)方程，在實(shí)際計(jì)算時(shí)一方面考慮了運(yùn)動(dòng)模態(tài)之間的耦合，另一方面在計(jì)算水動(dòng)力時(shí)，考慮了非線性因素的影響。 froude - krylov力、輻射力、繞射力中的水動(dòng)力系數(shù)隨吃水瞬時(shí)變化，靜浮力的計(jì)算精確到船體瞬時(shí)濕表面積，最后用四階龍格?庫(kù)塔方法在時(shí)域內(nèi)求解船舶運(yùn)動(dòng)方程，并進(jìn)行了載荷計(jì)算。 - On the basis of this analysis the radiation and diffraction forces of the ship are calculated using these three methods and compared . at the same time vertical ship motions in regular wave are solved by these three methods . the results are compared to test each method ' s availability and suitability , thus the theoretical basis of optimize design of sea - keeping performance is provided
分別介紹了二維切片法、高速細(xì)長(zhǎng)體理論和三維理論的基本原理，分析了三種不同方法各自的適用性，在此基礎(chǔ)上分別計(jì)算了船舶的輻射力和繞射力，比較了這三種方法的計(jì)算結(jié)果，為不同營(yíng)運(yùn)目的的船舶耐波性計(jì)算提供陜速有效而實(shí)用的計(jì)算方法；同時(shí)應(yīng)用三種方法計(jì)算了船舶在規(guī)則波中的垂向穩(wěn)態(tài)運(yùn)動(dòng)響應(yīng)，比較三種方法的計(jì)算結(jié)果，測(cè)試各種方法的有效性和適用性，為船舶耐波性的優(yōu)化設(shè)計(jì)提供原始的理論基礎(chǔ)； 2 - It's difficult to see diffraction force in a sentence. 用diffraction force造句挺難的
