专家系统(expert system)是人工智能技术应用中最成功的一个分支。在机械产品设计开发过程中有效地运用专家系统,对提高产品质量、缩短产品设计周期、降低开发成本等具有重要意义。 图形处理及工程计算,特别是后者是开发机械设计专家系统所面临的主要难题。本文在系统研究MATLAB软件的强大计算功能和专用工具箱的基础上,尝试利用MATLAB完成机械设计专家系统中的工程计算问题。 基于这种思路,本文着重探讨了利用Microsoft公司的Visual C++6.0编制前台程序时,通过MATLAB所提供的各种接口功能,调用MATLAB软件的计算功能,解决机械设计专家系统中的工程计算问题 并以Visual C++6.0和MATLAB作为系统的集成开发环境,尝试开发了适用于Windows98/NT/2000操作系统下的外螺纹轧机轧制系设计专家系统。 本系统中,利用后台的MATLAB计算引擎对用户提交的初始参数进行计算推导,从而帮助设计者完成主要设计参数的计算和结果分析任务,提高了设计计算的精确性和效率。(Expert system (expert system) is the most successful application of artificial intelligence, a branch. In the process of mechanical product design and development of effective use of expert systems, to improve product quality, shorten product design cycles, reduce development cost is important. Graphics and engineering calculations, especially the latter is the development of mechanical design expert system faced major problems. MATLAB software in the system this powerful computing capabilities and a dedicated toolbox, based on the attempt to use MATLAB to complete mechanical design expert system engineering computing problems. Based on this idea, this paper focuses on the use of Microsoft s Visual C++6.0 when the foreground program compiled by MATLAB provides a variety of interface functions, call the MATLAB software, computing, mechanical design expert system to solve the problem of engineering calculations and to Visual C++6.0 and MATLAB as the system s integrated development envi)
