自顶向下的计算机辅助工业设计几何建模研究

Research on Top-Down Geometric Modeling in Computer Aided Industrial Design

  • 摘要: 基于通用设计理论,研究了自顶向下的计算机辅助工业设计几何建模过程,采用面向设计演进过程的元模型和面向工业设计方面各侧面的子模型作为组织几何建模过程的抽象层次.提出了基于有向图的层次化几何信息模型,实现了对设计历史及意图的记录、不同层次几何信息间的关联以及按照元模型和子模型组织的自顶向下的计算机辅助工业设计几何建模过程.

     

    Abstract: On the basis of general design theory, metamodel focusing on the design evolution process and aspect-model focusing on industrial design views are used as abstract levels to organize the geometric modeling process in industrial design. The hierarchy of geometric information represented in the form of directed graph is used to record the design intents and design history, it reflects the relations among geometric information in different abstract levels. Feasibility of such an approach is verified in the layout of a long head car with front-mounted engine and rear driving box.
