机械产品方案创新设计的CAD方法及实现模型

文中将机械产品方案创新设计分为三个层次（变异功能结构、发明新型机构解、组合机构），建立了产品方案创新设计模型。同时，提出功能结构描述规则和寻求功能元机构解及机构组合的系统化方法，制定出计算机能够识别的产品方案创新设计模式和便于用计算机程序语言描述的设计过程。实现了计算机辅助产品方案的创新设计。

The Method and Model of computer Aided Creation Design of a Mechanical Product Scheme

The creation design of a mechanical product sheme can come true by changing function structure,inventing new mechanisms and combining mechanisms. This paper builds the creation design model of a mechanical product scheme, brings forward the rules of describing function structure and the systematism methods of searching mechanisms that realize specified function and combining them. In the methods,computer can identify a creation design mode of a mechanical product scheme and design process can be described by program.
