摘要
当前我国中小企业的零部件重用还存在着较多困难,主要是重建零部件知识库工作量大及知识检索困难.为此,给出粗细粒度双网映射的零部件设计知识重用方法.在中小企业现有产品零部件图形数据库和CAD设计基础上,建立包括零部件图形数据库内容的树状知识网,称之为细粒度知识网,该树状知识结构与原数据库的结构相符合.另外构造一个纲目式粗粒度网络状零部件知识网,并用本体OWL表示.该双网映射零部件知识重用可用于中小企业基于变型设计或自适应产品零部件设计,或将来基于Web的中小企业产品设计重用.减速器的零部件设计重用实例表明了所提的双网映射的零部件设计重用方法的有效性和实用性.
Currently,there are still many problems about the parts reuse for small and medium-sized enterprises（SMEs） in China.The main problem is that the reconstruction for parts library is an arduous work and the retrieve of the design knowledge is difficult.To solve this problem,a coarse-fine-grained and dual-network mapping design knowledge reuse method for parts design reuse is proposed.On the basis of the current graphic databases and CAD in the SMEs,a fine-grained tree＇s structure knowledge network for parts is constructed which is called fine-grained knowledge network.The tree＇s structure is consistent with the structure of the original database.A coarse-grain network＇s structure knowledge network with outline-style for parts is also constructed which is expressed by OWL.The dual-network mapping design knowledge reuse method for parts design reuse is applied to variant design or adaptive design of SMEs,and it also can be used for future Web-based design reuse for SMEs.The design reuse example of reducer shows that dual-network mapping design reuse method for parts is effective and practicable.
