支持协同概念设计的产品信息构模

Product Infonnation Modeling for Supporting Collaborative Concept Design

现代机械产品设计越来越基于协同,产品信息的表征是支持不同设计者之间通信和协同的关键之一。本文提出了面向对象的产品信息模型,它不仅包括了产品的几何和物理信息,还包含了功能、行为、性能等非几何信息,能清晰表达产品及其属性的层次结构和关系,满足了协同概念设计中产品信息共享的需要。

Modern mechanical product design is becoming increasingly collaboration intensive. The representation of prod-uct information is one key issue of supporting communication and coordination of different designers in collaboration. This pa-per proposed an object-oriented product information model. It contains not only the geometric,physical properties of the prod-uct, but also other non-geometric information such as function, behavior and performance, etc. Moreover,it characterizes the hi-erarchical structure of the different properties of product and the relationship among them clearly. This satisfies the requirement of the product information sharing during the process of the col-laborative concept design.
