摘要:

描述了将有限元方法集成到基于人工智能的焊接工艺专家系统中的关键技术,基于人工神经网络的焊接工艺专家系统以C++BUILDER作为开发工具,通过客户端调用软件组件、多线程技术和模型扫描,使有限元分析软件ABAQUS融合到焊接工艺专家系统中,完成了焊接工艺向有限元分析边界条件的自动转换,实现以有限元分析作为专家系统中的中间数据导出,为系统决策提供基础数据。

Abstract:

The article describes the key technology that finite-element analysis is integrated in welding technology expert system based on artificial intelligence.In C++Builder developing environment,through client program calling software-component,multi-thread technology and model scanning,finite-element analysis software ABAQUS may be a part of welding technology expert system.The automatic conversion from Welding Procedure Specification to boundary conditions of finite element analysis can be achieved.Finite element analysis software offering basis data as middle-deduce-reasoning to expert system decision-making may be realized.

Key words: software component multithreads technology model scanning element expanding welding technology expert system
