基于知识工程的岸浅桥数字化样机设计系统

摘要

提出了一种岸边集装箱起重机的数字化设计方法,这种方法以专家系统和模犁库为支撑,构建基于知识工程的岸边集装箱设计系统.论述了数据库和计算方法为基础的专家系统,并且讨论了模型库的结构,标准件、外购件的选择方法.由基础设计参数、设计约束、设计规则寻找最适合的型号和尺寸驱动模型.通过计算后的数据到专家系统中寻找型号,再从模型库中获得此型号装配,并自动生成设计说明书和施工图纸等,解决了目前CAD技术在岸边集装箱起重机设计计算过程中错误和数据共享的问题,实现了计算、结构设计、工艺设计、产品数据管理一体化过程.%This paper proposes a digital design method of quayside container crane based on expert systems and model base. It builds a design system of quayside container crane based on knowledge engineering. This paper discusses expert systems based on data base and calculation, and discusses structure of model base, standard parts, outsourcing parts selecting. It searches for the most suitable type and size driver model according to the basic design paramete, designs restriction and regulation. After calculation, it looks for type from expert systems, and then gains this type from model base for assembling, then generates design specifications and construction drawings automatically. This design solves the calculation and data sharing during problems during the quayside container crane design with CAD technology. And it realizes that calculation, structural design, process design, product data management integration.
