摘　　要：为解决分布式异构产品数据管理系统和计算机辅助设计平台中产品设计模型之间设计修改的感知问题,针对模型间设计相关性的不同紧密程度,划分模型级和特征级两种不同灵敏度的协同设计模型感知。利用感知路由描述表,建立分布式产品数据管理系统之间的感知关联;利用模型特征相关性描述表,建立异构计算机辅助设计平台下模型间的特征级感知关联。同时,设计了通信层、接口层、模型层、特征描述层和路由描述层的体系结构,解决了特征级感知和感知通信的问题。最后,针对所设计体系结构,分析了模型级和特征级模型感知的实现流程。To solve the problem of the collaborative perception among models that were distributed in heterogeneous Product Data Management （PDM） and Computer Aided Design （CAD） platforms, the two--grade multi--sensitivity collaborative design perception models were proposed. Model perception and feature perception models were divided into sensitivity according to the design correlation degree. Perception correlations among distributed heterogeneous PDM systems were established by a perception router description table, and the perception correlations among heterogeneous CAD models were established through a model feature correlation description table. A system structure was designed as five tiers of communication tier, interface tier, model tier, feature description tier, and router description tier. It was designed to realize the feature--grade perception and perception communication. Finally, according to the structure, the implementation processes of the model perception and feature perception were analyzed.
