摘　　要：提出了一种新的在船舶设计阶段光顺船体型线的自动光顺方法。文献中有两类光顺方法:局部光顺法和整体光顺法,文中的光顺方法引入控制点的权值,从而建立了局部光顺法和整体光顺法的统一优化模型。为了提高型线光顺效果,该光顺方法使曲线的应变能和曲率的变化最小,并在优化过程中保证船体型线的几何特征不变。应用该方法光顺典型的船体横剖面曲线,表明可得到满意的光顺效果。There are two kinds of fairing scheme： local fairing and global fairing. In this paper, a new automatic fairing approach to be used at the design stage to fair hull lines is presented.A weight of the control points is introduced into the optimization process, thereby the local fairing and global fairing can be in a uniform optimization model.To create high-quality hull lines,the new fairing approach is based on an optimization approach in which a fairness measure related to bending energy as well as the variation of the curvature is the objective function and a set of constraints is used to ensure the geometric characteristics of the final hull lines.As an example,the approach is applied to a typical ship section curve and it is shown that the approach can produce the hull lines with significantly im- proved fairing characteristics.
