【摘要】 本文所研究项目来源于国家重点基础研究973计划项目《现代设计大型应用软件的共性基础》,其中湖南大学负责子课题《工业(造型)设计专门知识辅助设计系统》。主要研究内容和目标是汽车造型专门知识的获取、表达;设计情境知识框架模型及案例情境模块的构建;建立基于案例的汽车造型设计系统原型——CBAS(Case-base Automobile Styling)系统。本论文的研究主要围绕基于案例的汽车造型知识获取和表达展开。基于案例推理的思想主要研究如何获取有效的汽车造型知识,以及汽车造型知识的有效表达方式。研究利用汽车造型特征线对汽车造型进行分析,实现了汽车造型知识的获取。利用情境和角色框架,实现了汽车整车和造型特征知识的表征。从而实现了为CBAS系统构建知识库的目标。本文基于造型特征和汽车造型特征线的概念,通过实验发现特征线是汽车造型设计知识的来源和载体。通过特征线的归纳和分类,提取了20条被认为是对汽车造型产生重要影响的特征线。在对特征线的描述中,引入了角色和情境对其进行分析和表征。在六元组的角色结构上,建立了汽车造型情境的风格情境、品牌情境和类型情境三种情境模式,实现特征线的知识表征。研究提出了一种基于特征的汽车造型知识获取的理论与方法。更多还原

【Abstract】 The research is part of 973 Research Project -- The Knowledge-base Industrial Design Assistant System. It emphasizes on the capture and representations of the Specific Auto Design Knowledge, the composing of the frameworks on the case scenarios model and finally the establishing of the CBAS (Case-base Automobile Styling) system .In this thesis the research makes a great effort to capture and represent the case-based automobile form knowledge. The case-based Reasoning theories concern how to get the effectual automobile form knowledge and the efficacious representations of it. Using the automobile form feature line to analyze the automobile form, based on the role and the scenario framework, this paper implements the capture and representations of the automobile form knowledge and builds the metadata-base for CBAS .As founded that the feature line is the origin and the carrier of the automobile form knowledge through the experiment analyze, this paper brings forward the concept of the form feature and the automobile form feature line. By concluding and sorting the 20 key feature lines, this thesis advances a feature-based theory and method of automobile form knowledge capturing. Trough six elements structure of the role and three automobile form scenario modes, which are style scenario、brand scenario and type scenario, the automobile form knowledge is represented.更多还原
