基于本体的零部件设计重用及系统实现研究

Research on system of design reuse for parts based on ontology

针对零部件设计重用问题,给出了零部件的本体表达框架及零部件本体建模的方法。研究了零部件信息的本体检索、持久化存储等关键技术。采用J2EE平台技术开发基于Web的本体零部件设计重用系统原型,通过SPARQL本体查询语言实现了零部件信息的语义检索,采用Jena提供的开发包将本体信息持久化保存到MySQL数据库中,最后通过工程机械常用的设计重用实例验证了系统的可行性与有效性。

Design reuse of parts plays an important role in product design.The major difficulty of design reuse of parts is that the information of parts is difficult to express,manage and retrieve.The design reuse of parts based on ontology was studied.A framework of parts information expression and an approach of ontology modeling were proposed.The key technologies of retrieval and storage ontology information were given.Lastly,a reuse system prototype for parts was designed,and an example was given to verify the fe...
