基于AutoCAD面向对象的轻型钢结构有限元分析

Finite Element Analysis of Light Steelwork Based on AutoCAD Object-oriented

提出了一种基于AutoCAD面向对象技术的轻型钢结构有限元分析方法。首先采用面向对象的技术建立轻型钢结构的计算机表示模型,在利用ObjectARX2000开发平台实现三维钢结构的结构自动设计的基础上,直接访问AutoCAD的数据库,提取并计算有限元的必要数据,利用面向对象的方法构建有限元分析所需要的类。最后,进行了实例化。

The paper introduced an approach of finite element analysis of object-oriented light steelwork based on AutoCAD. Firstly,based on the object-oriented technology, a computer model of the light steelwork is established. Then,based on the intelligent design,a light steelwork is developed by ObjectARX2000, it accesses the AutoCAD database, abstracts and calculates the necessary data for FEM and builds the necessary classes for finite element analysis by means of object-oriented technology. Finally,an instance is given to show the programming of finite element method.
