语义过渡特征建模和形状计算方法的研究

Research on modeling and computing shape of semantic blend

针对当前系统边界表示法描述过渡特征的不足,对过渡特征的附加面作了深入的研究,提出一种新的过渡特征建模和确定过渡特征形状的方法,从而使过渡特征的语义得到有效地维护。该方法减少了永久命名问题对过渡特征的影响,并且不要求在FFDPs配置中提前指定,定义的参数可以直接映射到FFDPs配置,定义的特征元素控制过渡特征的形状。

In order to solve deficiencies about describing blend in the brep,deeply researched the attachment of blend feature,the paper presented a new method to model and computed the shape of the semantic blend,and blend feature semantic could be maintained through validity maintenance.The method made the blend feature suffer less from the persistent naming problem,required no pre-defined configuration of FFDPs,parameters could be mapped to configurations of FFDPs,defining feature elements could be used to control ...
