| 中文摘要: |
| 基于IGES文件，提出一种能够方便嵌入至有限元分析（FEA）前处理平台中的平面图形最小独立封闭区域识别算法。该算法通过读取和整理CAD几何模型数据文件得到原始数据，并经过区域识别计算输出供FEA建模的数据文件。该算法已成功应用于轮胎FEA前处理平台中。 |
| 英文摘要: |
| Based on IGES（Initial Graphics Exchange Specification）file，the minimum independent
closed region recognition algorithm for planar graphics was proposed，which could be easily embedded in
finite element analysis（FEA） pretreatment platform. This algorithm obtained the original data by reading
and sorting out the data files of CAD geometric model，and output the data files for FEA modeling through
the region recognition calculation. This algorithm was applied in tire FEA pretreatment platform successfully. |
