基于特征的协同产品建模

产品模型是产品设计、制造的基础，存在于产品的全生命周期中。协同、并行的产品设计与制造需要与之相适应的建模系统。本文在总结了目前流行的一些产品建模系统后，提出一种适应于协同设计的建模方法；引入形状特征的概念，完成产品的形状特征建模；采用特征转换和映射工具将产品的形状特征模型转换为工程特征模型并映射到不同领域的应用中，以实现产品的协同设计与制造。

The Feature Based Cooperative Product Modeling

Product-model is the basis of design and production. It exists in the whole period of product. The simultaneous and collaborative development of product needs the corresponding product-models. In this paper, according to recent research and development in product modeling, a new method of product modeling that adapts to the cooperative design is introduced. Using the conception of form feature and the tools of transformation and mapping for feature, the engineering feature model of product is established and the specific representations of a product model can be obtained, in order to enable the designers to work cooperatively.
