机械零件设计的知识服务方法及系统实现

KNOWLEDGE SERVICE METHOD FOR MECHANICAL PARTS DESIGN AND SYSTEM IMPLEMENTATION

为了解决机械零件类知识资源难以被发现,获取效率低的问题,提出一种基于零件实例库的关联知识服务方法。根据知识间的从属关系,设计三种关联知识检索方法;基于相似度匹配算法,设计关联知识推送方法,并通过以上两种知识获取方法实施知识服务。设计并实现了机械非标零件设计知识服务平台,为非标零件设计过程中知识的共享和管理提供一个综合的网络服务平台。最后通过应用实例对该平台知识服务的应用效果进行了验证。

To solve the problem that the knowledge resource of mechanical parts category is hard to be discovered and is low in acquisition efficiency, we proposed a parts case library-based association knowledge service method. According to the subordination relation between the knowledge, we designed three types of association knowledge retrieval method, and based on similarity matching algorithm, we designed the association knowledge push method. By the above two knowledge acquisition methods we implemented the knowledge service. We also designed and implemented the knowledge service platform for non-standard mechanical parts and provided a comprehensive network service platform for knowledge sharing and management in the process of non-standard mechanical parts design. Finally, we verified the application effect of the knowledge service on the platform through application examples.
