| 中文摘要: |
| 提出一种改进的栅格法网格剖分算法,该算法综合了栅格法和Delaunay算法的优点,生成了四边形和三角形混合单元,保证了整体性能与局部性态最优,满足汽车覆盖件冲压成形模拟软件对有限元网格质量的需求。实践证明,本文提出的改进的栅格法网格剖分算法可行有效,生成网格的质量高,程序容易实现。该算法已经成功集成到商业化冲压成形模拟软件KMAS中。 |
| 英文摘要: |
| An IGMG(Improved Grid Mesh Generation) is proposed in this paper. The algorithm combines the advantages of grid algorithm and traditional triangulation Delaunay algorithm, it generates quadrilateral/triangle mixed elements that ensured the overall and local performance. The result meshes meet the quality requirements of finite element mesh for automotive panel stamping forming simulation software. Practice has proved that the IGMG to be robust, efficient, generating meshes with high quality and easy to be implemented in practical applications. The algorithm has been successfully integrated into the commercialized stamping simulation software ——KMAS. |
