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。
Abstract:
This paper studies the feature relat ionship based on const raint. First ly it analyses the relat ionship betw een constraints and it s products and influence on the product formation, and points out that ex pression of the feature relat ionship is important research f ield in parameter . Based on researching dif ferent const raint relat ionship among features, a graph called Feature Relat ionship Graph( FRG) is given to ex press these relat ionships and at t ributes. 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 eng ineering .
