面向对象板料成形有限元模拟软件的图形平台设计与实现

The Design and Implementation of an Object-oriented Graphics Software in the Finite Element System for Sheet Metal Forming

在板料成形有限元模拟软件系统中 ,图形平台是重要的组成部分。介绍了图形平台的设计与实现 ,并重点阐述了面向对象编程技术在软件开发中的实际应用 ,同时结合图形平台需要提供的功能 ,给出了图形平台各个类的继承关系和实现中的一些关键技术。实践表明 ,此平台具有较好的灵活性。

Graphics software is an important part of a finite element system for sheet metal forming. This paper presents the design and implementation of the graphic software and emphatically explains the application of the object oriented programming technology. Combined the function of the graphic software, the inherited relation of classes in the software and some key technique in implementation are also showed. It is proved that this software is of good flexibility, reliability and expansibility.
