摘　　要：基于表达设计意图和支持产品设计全过程的思想,分析方案设计和技术设计过程及产品信息的形成过程,提出支持产品方案设计和技术设计的产品模型。给出了产品组成结构、装配关系和结构设计3类产品信息的模型,其中结构设计信息包括装配特征、工艺特征和结构特征。列举并分析实现装配关系的装配特征实例,研究装配关系与装配特征间的功构映射,提出依据工程实际建立装配关系与装配特征间的稳定映射,实现产品设计知识的显示表达。最后用实例说明产品信息的传递和生成过程,验证该模型的有效性。Based on the idea that represents design intents and supports product＇s whole design process,the scheme design,the technique design process and the formative process of the product information was analyzed,proposing the product model supporting scheme and technique design.The product information model of the product structure,assembly relationship and the structure design was given,in which the information of the structure design includes assembly feature,process feature and assembly feature.The example of the assembly feature which realized the assembly relationship was enumerated and analyzed,and the function-structure mapping between assembly relationship and assembly feature was researched,the stable mapping between assembly relationship and assembly feature was proposed according to engineering practice,realizing the explicit expression of the knowledge of product design.At last,the process of the transmission and the generation of the product＇s information were illustrated by an example,and the validity of the model was verified.
