摘要
Based on the characteristic peculiarities of mechanical design expert systems (MDES), the design process pf gear box and its components is introduced and the gear box design expert systems (GBES)is established. GBES employs the methods of knowledge representation to indicate the knowledge-unit-rule-process, table-vector-process. By taking the advantage of knowledge unit's indicator, it can make the units of knowledge base to to combine to form a whole in the feature of trees and nets so that it can give deduction conveniently. The knowledge base of GBES is organized in hierarchy, which provides the efficient managerial systems of knowledge base. It makes the knowledge base convenient greatly for establishing and using. The assistant modules of GBES are written in FORTRAN and the part of expert systems is written in LISP. It explains the I/O among each module and the forms of independent application. The GBES systems have been put into preliminary, use in practice.
在论述机械设计家专家系统(MDES)特点的基础上,详细介绍了齿轮箱及其内部组件的设计过程,建立了齿轮箱设计专家系统(GBES)GBES采用知识元一规则一过程表一向量和过程的知识表示方法,利用知识元的指针可将知识元以树状和网状连为一体,以方便推理,GBES的知识库是用分层方式组织的,并提出了有效的知识库管理系统,这大大方便了知识库的建立与使用,GBES的辅助设计模块是用FORTRAN编写的,而专家系统部分则是用LISP编写的。最后介绍了各部分之间的接口和独运方式。GBES系统已初步在实际中应用。
