三体船相对于传统的大型船舶具有耐波性好、稳定性高、载货量大等优点，如何提升三体船的设计质量目前已经成为世界范围内船舶工业的重要研究方向。本文研究的内容是一种基于模块化理论的三体船总体设计方法，模块化设计理念是近年来兴起的一种新型设计理论，基于模块化设计理念能够有效降低船舶产品开发的周期，提升船用部件的复用性，使船舶产品的产品特性达到最佳。本文基于模块化设计理论，利用NURBS曲线进行型线拟合设计，完成三体船的特征曲面优化设计，并基于此进行了设计方案的流体动力学特性分析。
Compared with traditional large ships, trimarans have the advantages of good seakeeping, high stability and large cargo capacity. How to improve the design quality of trimarans has become an important research direction in the shipbuilding industry worldwide. The content of this paper is an overall design method of trimaran based on modular theory. The modular design concept is a new design theory emerging in recent years. The reusability of components maximizes the product characteristics of marine products. Based on the modular design theory, this paper uses the NURBS curve to carry out the profile fitting design, completes the optimization design of the characteristic curve of the trimaran, and analyzes the hydrodynamic characteristics of the design scheme based on this.
