注塑产品并行设计过程特征建模

在并行环境下 ,设计过程集成与产品信息集成两个环节互相关联。基于特征的产品信息模型在满足产品信息表达的完备性的同时 ,也应该满足设计过程不同阶段的不同需求。本文通过对设计问题不同阶段的特点及所需信息的分析 ,建立起并行设计环境下面向设计过程的注塑产品特征模型 ,并提出了区别于产品几何表达驱动设计方法的功能驱动设计方法。

Feature-based Modeling for Con-current Design Process of Plastic Injected Products

In concurrent engineering environment, the integrated design process works along with the integrated product information model. The feature based product information model should meet the different requirments in different design phases, as well as presenting sufficient product information. Based on the analysis of the design process, a design process oriented feature based model was developed to provide specific product information in different design phase. And the function driven design methodology is adopted for concurrent design.
