摘要
提出了一种真空镀膜机的模块化设计方法,这种方法以专家系统和案例库为支撑,构建基于知识工程的真空镀膜机模块化设计系统。论述了数据库和案例推理方法为基础的专家系统,并且讨论了知识体系的结构,模块化设计方法以及案例推理的方法。由基础设计参数、设计约束、设计规则寻找最适合的型号和配置。通过设计后的数据到专家系统中寻找型号,再从案例库中获得此型号配置,并自动生成设计式样书和物料清单等,解决了目前CAD技术在真空镀膜机设计过程中存在的错误以及数据共享的问题,实现了结构设计、工艺设计、产品数据管理一体化过程。
This paper proposes a modular design method of Vacuum Coating Machine based on expert systems and case base.It builds a modular design system of Vacuum Coating Machine based on knowledge engineering.This paper discusses expert systems based on data base and CBR,and discusses Knowledge structure,the modular design method and the method of CBR.It searches for the most suitable type and configuration according to the basic design parameter,designs restriction and regulation.After calculation,it looks for type from expert systems,and then get the configuration from case base,then generates design specifications and BOM.This design solves the calculation and data sharing during problems on the vacuum coating machine design with CAD technology.And it realizes that structural design,process design,product data management integration.
