面向自顶向下设计的装配模型研究

Study of Assembly Model for Top-Down Design

装配模型是支持数字化产品设计和制造的重要基础。设计人员通过装配建模表达产品的功能形状和设计师的设计意图。本文针对自顶向下设计模式对装配模型的特殊要求 ,提出一种面向自顶向下设计的装配模型 ,支持产品设计过程中的多种设计活动。给出了模型的维护方法 ,为自顶向下的装配设计提供了安全的数据支持。该模型为产品装配的自顶向下设计提供了良好的模型基础。

Assembly model is the important base of digital product designing and manufacturing. With the assembly model, designers can show the shapes and functions of products and express their ideas. To satisfy the special request of the top-down design pattern, an assembly model is built. It supports the design actions in design period. The methods are presented to maintain the consistency of the assembly model. This assembly model provides a good environment for top-down design.
