摘　　要：无压载水船舶作为一种新的船舶设计理念已经在国外展开了相关的研究,而在中国还研究甚少。就V型无压载水方案的型线设计变换进行研究,首次提出基于母型的横剖面面积曲线基本不变的V型无压载水型线设计变换方法。该方法对母型船的型线进行底部V型变换,使设计船舶的底部呈现一定的倾角,同时增大船宽。变换后设计船舶的横剖面面积曲线和母型船保持一致,变换方法简单可靠,在保证设计船舶的船长、设计吃水、排水量等参数基本不变的情况下,较好地解决了设计船舶型线的光顺性问题。As a new concept in ship design, ballast-free ship has been studied extensively abroad, but it is rarely mentioned in China. In this paper, the design and variation of the hull lines for this kind of ships were studied and a new design and variation method was proposed under the assumption that area of the mid-ship section equals to that of the mother ship. With this method, the hull lines of the bottom of the mother ship was changed into V-Shape, so that the designed ship has an inclined angle at the bottom with a wider breadth while the area of the mid-ship section was kept unchanged. The proposed new method is simple but reliable. It can obtain smooth hull lines for the design ship with the major factors unchanged, such as length, draught and displacement, etc.
