| 摘 要： | 将模糊理论应用到船体线型设计中，提出了一种新的横剖面面积曲线生成和线型变换法。特点是在给定方形系数 Ｃ_ｂ、浮心纵向位置 Ｌ_（ｃｂ）和傅汝德数 Ｆｎ后自动或人机交互地调整模糊权函数，生成一系列满足设计要求的船体横剖面面积曲线。在给定母型船后就能生成系列新船型供进一步优选，使计算机辅助船体线型设计更加灵活、方便和实用。２０００ｔ供油船、２８０００ｔ多用途船和１５００００ｔ油船的线型设计，证明了该方法的先进性和实用性。

| Abstract: | By using fuzzy theory in ship lines design, a new method is described which produces section area curve and transforms hull form. If Ca_bL_(cb).and Fn are known, a series of section area curves are generated which meet the requirements of design by transforming the fuzzy weighted functions. After a parent ship is provided, a series of new hull forms may be produced to meet the requirement of further optimization. It is proved that this method is feasible and practicable by calculating examples. |
