摘要: 为了提高语义特征建模系统约束求解的效率及系统的整体性能,提出了一种新的操作局部化方法。该方法使用特征语义表示法来描述产品模型中特征的各种信息,改进了细胞元模型对特征元素的管理机制,通过特征的“语义面”将局部特征从模型中有效地分离出来,通过创建临时特征的方法来实现模型的局部约束求解。该策略不仅可以完全满足在复杂模型中直接操作的需要,还可以大大提高系统的性能。实验表明该算法具有更强的适应性和实用性。

Abstract: To improve the efficiency of constraint solving and the performance of semantic feature modeling system,a new method is presented.It represents all of information in features by the feature semantic representation,enhances the management mechanism of feature’s elements,separates the local features from product models effectively by semantic faces,and achieves the local constraint solving by creating the provisional cells.This method can not only solve the problem of direct manipulations in a complex model,but also enhance the efficiency of semantic feature CAD system.Experiments on computer show that this new method is more adaptable and practicable.
