船舶型线设计是船舶设计的重要环节，它决定了船舶的外形、性能和航行特性。传统的船舶型线设计存在设计周期长、效率低、精度不高等问题。近年来，随着计算机辅助技术的发展，船舶型线设计逐渐引入了计算机辅助设计（CAD），利用CAD软件进行船舶型线的参数化设计和三维建模，能够显著提升船舶设计和优化的效率。通过数值模拟和优化算法，设计师可以对船舶的流体力学特性进行分析和优化，以提高船舶的性能和航行特性。本文介绍NURBS曲线拟合的基本原理，并以船舶的阻力特性为设计约束条件，研究计算机辅助的船舶型线设计，具有实际应用价值。
Ship profile design is an important part of ship design, which determines the shape, performance and navigation characteristics of the ship. The traditional ship profile design has some problems such as long design period, low efficiency and low precision. In recent years, with the development of computer-aided technology, computer-aided design (CAD) has been gradually introduced into ship profile design. Using CAD software to carry out parametric design and three-dimensional modeling of ship profile can significantly improve the efficiency of ship design and optimization. Through numerical simulation and optimization algorithm, designers can analyze and optimize the fluid dynamics characteristics of ships to improve the performance and navigation characteristics of ships. In this paper, the basic principle of NURBS curve fitting is introduced, and the computer-aided ship profile design is studied with the resistance characteristic of ship as the design constraint.
