摘　　要：通过对DXF文件结构和哈希查找算法的详细剖析,在UNIX平台下运用C语言设计了基于哈希表的DXF文件信息读取方法,并将其运用到冲压成形专用非线性有限元仿真软件包SHEET-FORM ING中,解决了其与CAD软件之间缺乏数据流联系的"孤岛"现象,从而提高其有限元模型的建模效率。A method of Data - extraction from DXF is designed with C Language in the platform of UNIX, which is based on the analysis of data structure of DXF file and hashing algorithm. Then it is applied to SHEET - FORMING, a special punch - forming non -linear FEM analysis software package, which solves the phenomenon of island＇that no dataflow communication exists betwnen SHEET - FORMING and CAD software, and improves the modeling efficiency of FEM.
