铁路客车设计参数的交互系统

Interactive System of Parameters for Passenger Car Design

分析了ＡＵＴＯＬＩＳＰ有关数据交互的方法及其用于铁路客车参数交互中所遇到的问题；运用关系数据库的基本原理和模块化设计思想，阐述了铁路客车设计参数交互系统的数据库与专家经验知识数据库的建立方法及如何利用ＡＵＴＯＣＡＤ和ＡＵＴＯＬＩＳＰ的功能，实现成百上千个数据的快速交互设计，从而为开发铁路客车参数化设计系统解决了一个技术问题．

Presents the problems we met in the interactive design of railway passenger car parametersby use of the interactive methods of AutoLISP, then exponds the way how to build up data baseof the interactive system of parameters for railway passenger car design and of the expert experi-ence according to the principle of related data base and the idea for modularity design,and clarfiesthe way how to use fonctions of AutoLISP and AutoCAD to achive the interactive design ofthousands of parameters. Therfore solves, an important technical problem for developing the systemof parameterization in railway passenger car design.
