摘  要:针对装配产品变型设计过程中的尺寸约束问题,提出了装配产品中零件的信息模型.研究了装配产品变型设计的基本原理,根据装配产品构成零件之间的配合关系类型,定义了一组基本的约束集,建立了反映各个约束集中构成零件之间关联关系的尺寸关系模型,与事物特性表技术相结合,实现了装配产品从上至下的变型设计过程,并以装配产品承载轮系为对象进行了验证.结果表明,零件信息模型和装配产品构成零件之间的尺寸关系模型满足变型设计过程中尺寸传递的需求,可以支持装配产品的变型设计.Aimed at the issue of dimensional constraint in the process of assembly variant design, a part information model of assembly was presented. The basic principle of assembly variant design was researched. A set of basic constraint groups were defined according to the mating relationship type among constituent parts of assembly, and the dimensional relationship model reflecting the relationship among constituent parts of each constraint group was established. With the help of tabular layouts of article characteristics technology, the top-down variant design process of assembly was realized. The feasibility of the model was verified through the variant design case of assembly trolley. The results show that the part information model and dimensional relationship model among constituent assembly parts can satisfy the requirement of dimensional transferring during variant design process, and support the variant design of assembly.
