大型通用远洋舰船模型的数字建模与模型制作

Digital Modeling and Physical Fabrication of Large General Seagoing Vessel Model

摘要: 在现代船舶工程教育高质量发展的背景下，对船海专业人才的工程实践能力提出了更高的要求。然而当前高校普遍存在船海专业理论与实践脱节、学生应用工程能力培养缺失的问题。船舶模型制作作为连接理论与实践的核心教学环节，在提高学生综合实践能力有着独特的作用。本文以大型通用远洋舰船为研究对象，设计并实践了一种“参数获取–三维建模–CFD兴波仿真预验证–物理模型制作”的模型制作方案。基于官方公开资料通过SolidWorks三维建模软件构建了1:138比例的三维参数化模型；再利用Fluent流体仿真软件完成了大型通用远洋舰船在三种不同流速下的CFD兴波仿真；最后通过手工制作与3D打印完成了实体模型制作。试验结果表明，该制作方案能系统性的培养学生的工程能力与实践能力，同时能为船海专业的实践教学提供可供参考的案例。

Abstract: Under the strategic layout of building maritime power, higher requirements are put forward for the engineering practical ability of marine engineering professionals. However, colleges and universities currently generally have the problems of disconnection between theory and practice in naval architecture and ocean engineering majors and the lack of training for students’ applied engineering ability. As a core teaching link connecting theory and practice, ship model making plays a unique role in improving students’ comprehensive practical ability. Taking t large general seagoing vessel model as the research object, this paper designs and practices a model production scheme of “parameter acquisition-three-dimensional modeling-CFD wave-making simulation pre-verification-physical model production”. Based on official public data, a 1:138 scale three-dimensional parametric model is constructed by SolidWorks 3D modeling software, and then Fluent fluid simulation software is used to complete the CFD wave-making simulation of large general seagoing vessel model under three different flow velocities. Finally, the physical model is finished by manual production and 3D printing. The test results show that the production scheme can systematically cultivate students’ engineering ability and practical ability, and provide a reference case for the practical teaching of marine engineering majors.
