| 中文摘要: |
| 为了实现需求驱动的结构变异设计，提出了多粒度移植结构的划分与再生技术。结构变异设计是在现有零件基础上移植多粒度结构，改变零件的拓扑关系，移植结构库的构建是复杂零件结构变异设计的基础。针对多粒度移植结构库中大量的移植结构，引入变精度粗糙集，以知识为载体储存移植结构的属性信息，通过变精度粗糙集对知识粒度进行划分，从而实现多粒度移植结构的划分与再生，为复杂零件的变异设计提供基础。结合注塑机产品的结构变异设计，构建了注塑机产品的多粒度移植结构库。 |

| A technique of partitioning and regenerating multi granularity transplantable structures was proposed to achieve the structural variant design, a demand driven method characterized by modification of the topological relations of existing parts through transplantation of multi granularity structures, with the construction of a transplantable structure library being its foundation for structural variant design of complex parts. The variable precision rough set was introduced to the transplantable structure library for its abundant transplantable structures. The attribute information of transplantable structures was stored as the knowledge and the knowledge granularity was divided through the variable precision rough set, thus, the partition and regeneration of multi granularity transplantable structures were implemented, and the feasibility for implementation of structural variant design of complex parts was achieved. A multi granularity transplantable structure library of an injection molding machine was developed to testify the proposed method for the structural variant design. |
