| 中文摘要: |
| 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-FORMING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. |
| 英文摘要: |
| 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 between SHEET-FORMING and CAD software,and improves the modeling efficiency of FEM. |
