基于造型三角形的大型游艇上层建筑造型研究及设计实现

Research and Design Implementation of Large Yacht Super Structure Exterior Modeling Based on Shape Triangle

文章提出造型三角形概念,并基于造型三角形对大型游艇的主尺度和造型参数作统计分析,通过已有游艇的造型设计特点逆向研究,量化研究大型游艇造型美学中的一般数学规律,使用贝塞尔曲线、NURBS曲线对游艇上层建筑中的曲线进行几何表达,并利用CATIA二次开发技术,开发了针对游艇上层建筑设计的平台,该平台可以根据要求快速创建游艇上层建筑三维立体模型,提高了在技术设计和施工设计阶段中游艇外观造型的设计效率。

The concept of shape triangle is put forward and based on it the statistical data of large-yacht is summarized to carry out reverse research method for existing yachts aiming to find the common mathematic rules in exterior design. The geometric Bezier Curves and NURBS are used to express the curves in yacht superstructure outlines. Superstructure Design System（SDS） is developed by second development of CATIA and this system can be used to design the curves of superstructure and create 3D model which can help to improve the efficiency of yacht exterior design in technique design stage and production design stage.
