摘　　要：近几年NURBS和相关技术的快速发展,使得船舶外形越来越多地使用NURBS表示,在参数化设计中的解决方式有很多种,但是选择最优的解决方案非常重要。针对船舶纵向参数优化问题,提出一种以NURBS表面为基础的纵向参数优化算法,并对船舶纵向参数优化算法进行研究。本文给出船舶垂直参数化的基本思路,并与NURBS表面构建法相结合,编制了一种用于船舶垂直参数化表面构建的程序。最后,用NURBS表面法确定船舶垂直方向的模型,并与表面曲线法相比较,证明了NURBS表面法可以精确、迅速地确定船舶垂直方向的模型。In recent years the rapid development of NURBS technology and related technologies has led to an increas-ing use of NURBS representation for ship shapes.There are many solutions in parametric design,but choosing the optimal solution is crucial.A longitudinal parameter optimization algorithm based on NURBS surfaces is proposed for the optimiza-tion of ship longitudinal parameters,and the optimization algorithm for ship longitudinal parameters is studied.This article provides the basic idea of ship vertical parameterization and combines it with the NURBS surface construction method to provide a program for building ship vertical parameterized surfaces.Finally,an example was given to use the NURBS sur-face method to determine the model of a ship's vertical direction,and compared with the surface curve method to prove that the NURBS surface method can accurately and quickly determine the model of a ship's vertical direction.
