面向机械创新设计的概念结构模型

Conceptual structure model for mechanical creative design

在机械创新设计中 ,结构设计是一个不同抽象层次结构的演化过程 ,但目前基于特征的机械结构模型还难以适应结构演化的需要 .文中从结构抽象与演化特征出发 ,提出了面向机械创新设计的概念结构模型 ,将结构信息统一用逻辑方法在概念模型中表示 ,而装配模型、零件模型和几何模型则由概念模型产生 .该模型所具有的动态性使其既满足多抽象层次表示机械结构的需要 ,又符合设计思维的要求 .

In mechanical crea tive design, structure design is an evolving process between abstract levels. Ho wever, structure evolution is not satisfied by feature-based models available. Based on the characteristics of structure abstraction and evolution, this paper presents a conceptual structure model for mechanical creative design, in which s tructure infomation is logically presented in the conceptual model, but the asse mbly model, part model and geometric model are engendered on the basis of the c onceptual model. The dynamic feature of the model satisfies both the needs of th e presentation of mechanical structure with many abstract levels and the design thinking pattern.
