异构环境中基于特征关系的产品建模方法研究

An Approach of the Feature Relationship－Based Product Modelling for the Integration of Heterogeneous CAD Systems

基于特征的产品数据交换的完整性、一致性是异构集成环境下亟待解决的一个关键问题。该文在给出异构集成交换平台模型的基础上，提出了一种建立在平台上的基于特征关系的产品建模方法。该文试图从较高的层面上解决异构环境下基于特征的产品信息交换问题，以避免异构系统间的数据差异。该文在给出产品的交换平台模型的基础上，研究了基于特征关系的产品数据模型。最后分析了该模型的优点与尚需改进的地方。

： It is vital to the feature－based product data exchange with integrality and identity for the integration of heterogeneous CAD systems．An approach of feature－based product data exchange platform is presented，and a feature relationship－based product model is developed for the data exchange platform．This paper is trying to perform the product data exchange at high level of the product information as well as to avoid the data diversity among the heterogeneous CAD systems．Based on the product data exchange platform model the feature－based product data model is discussed in the paper．Finally both the advantage and disadvantage of the approach are pointed out．
