摘要
面向对象的设计克服了程序结构复杂、复用性、维护性和扩充性差的问题,而成为有限元程序设计开发的发展方向.本文对刚塑性有限元模拟问题首次用面向对象的方法进行了系统地研究:以面向对象有限元理论为基础,利用UML建模语言,研究了刚塑性金属有限元模拟的对象和有限元分析类库的建立;基于VC++编程平台,开发了薄壁管数控弯曲有限元模拟可视化软件原型,并对开发中的关键技术问题进行了介绍.结果表明,所建立的有限元分析框架通用性良好,所开发的模拟系统能方便地嵌入参数优化、CAD/CAM模块和可视化前后处理,从而显示出良好的扩充性和可维护性.
Due to the capability of overcoming complication of code structure and strong coupling among modules, also reversely abilities of reuse and maintenance, OOP(Object-Oriented Programming)has been being one mighty means for FEM programming. In the paper, Rigid-Plastic FEM simulation has been researched systematically using OOP method: Based on OOP theory, employing with UML language, objects and classes for Rigid-Plastic FEM simulation have been established; the NC Thin-Walled Tube Bending Simulation System was developed on VC^(++)programming panel, then key issues in the course of developing are also introduced. The result indicates that the FEM analysis framework established is suitable for most purposes, and the simulation system has capability of well abilities of reuse and maintenance embedded with CAD/CAM and others modules conveniently.
