摘要: 通过对实体零件在装配层次上的抽象以及基于抽象零件的装配建模,建立了产品符号装配模型。针对概念产品装配结构的定性特性,通过对符号装配模型中零部件之间空间位置关系的定性描述,建立了面向概念设计的产品装配结构定性模型。讨论了装配副、符号装配关系、定性几何约束和定性几何约束图,并结合实例介绍了概念产品装配结构定性模型的建立过程。

Abstract: By abstracting of solid parts in assembly level and assembly modeling based on the abstracting parts, product sym-bol assembly models are presented. Aiming at the qualitative features of conceptual product structures, by qualitative descri-bing of space position relations among parts in symbol assemb-ly models, the assembly qualitative models in concept design are presented. Assembly pair, symbol assembly relation, qualit-ative geometry constraint, qualitative geometry constraint graph are discussed and qualitative modeling examples are presented.

Key words: Assembly modeling, Concept design, Qualitative model
