减速器三维参数化CAD专家系统的知识库与推理机的构建

在减速器三维参数化CAD专家系统中,在分析面向对象的知识类型的基础上,采用数据库形式、产生式形式、程序源代码形式以及混合形式的方式建立了系统的知识库,在分析减速器的设计过程的基础上,提出了由系统级的推理、模块级推理、子模块级推理、控件级推理所构成的分层次的多级推理机的推理模型,并采用以松耦合为主,紧耦合为辅的耦合方式将知识库与推理机紧密地联系起来。

The establishment of knowledge base and reasoning machine of reducer three-dimensional parametric CAD expert system

In the reducer three - dimensional parametric CAD expert system, establish the knowledge base by adopting the style of database, production rule, program code and hybrid on the basis of analyzing the type of Object Oriented knowledge. Introduce the multilevel - reasoning model of reasoning machine composed by system level, module level, sub - module level and control level on the basis of analyzing the design process of reducer. Combine knowledge base with reasoning machine by adopting the coupling form of loose - coupling as main and tight - coupling as auxiliary.
