基于FREESHIP的V型无压载水船研究

摘要

Based on V-shape hull theory the non ballast water ship is researched with the ship design software FREESHIP. A method determining the bottom inclination angle is proposed for the first time and a new method for line conversion at non-parallel part of the body is addressed. A bulk carrier is taken as the mother ship and converted into a non-ballast water ship. From a comparative study on floating state, stability and sea keeping between the design ship and the mother ship, it is found that performance of the design ship is better than that of the mother ship with few exceptions.%基于V型船体理论，通过船舶设计软件FREESHIP进行无压载水船设计，以一艘散货船为母型船进行实例变换。首次提出了确定船底倾角的方法和非平行中体部分型线变换新方法。分别对设计船与母型船的浮态、稳性、耐波性进行对比研究，发现除个别情况外，设计船的各项性能均比母型船好。
