摘要
该文对基于约束的特征关系进行了深入研究。首先分析了约束与设计意图的关系及其对产品构成的影响，指出特征高层关系的表示是特征参数化的重要内容。在分析特征之间存在的各种约束关系的基础上，提出了用一种图———特征关系图（Ｆｅａｔｕｒｅ Ｒｅｌａｔｉｏｎｓｈｉｐ Ｇｒａｐｈ ，简写为ＦＲＧ） 来表示这些关系及其属性，并给出了对ＦＲＧ 图管理的具体算法。该文的研究结果在某ＣＩＭＳ工程中的产品建模系统ＸＬＭＦＣＡＤ 中得到了应用。
This paper studies the feature relationship based on constraint. Firstly it analyses the relationship between constraints and its products and influence on the product formation,and points out that expression of the feature relationship is important research field in parameter . Based on researching different constraint relationship among features, a graph called Feature Relationship Graph(FRG) is given to express these relationships and attributes. Finally it discusses the detail algorithm to manage the FRG. The result of the paper has applied in the product modeling system (XLMFCAD) of a CIMS engineering.
