According to the character of die shape, based on the mathematical model of multiple trimmed parametric surfaces, which is created by CAD/CAM system, an algorithm for generate mixed mesh of triangles and quadrilaterals for finite element analysis is presented. The trimmed parametric surfaces are discreted into polygons, which are controlled by the parameters of maximum edge length, minimum edge length, distance tolerance and angle tolerance, etc. The adjacent relation between surfaces is found and merged...

According to the character of die shape, based on the mathematical model of multiple trimmed parametric surfaces, which is created by CAD/CAM system, an algorithm for generate mixed mesh of triangles and quadrilaterals for finite element analysis is presented. The trimmed parametric surfaces are discreted into polygons, which are controlled by the parameters of maximum edge length, minimum edge length, distance tolerance and angle tolerance, etc. The adjacent relation between surfaces is found and merged by surface curves, consequently, a model represented by boundary is created, the polygons are updated by surface curves, and mixed mesh is generated by these polygons. The resultant mesh is conformal, without crack and overlap between the adjacent surfaces.

根据冲压模具形状特点 ,对由CAD CAM系统建立的冲压模具的多裁剪参数曲面数学模型 ,提出了一种符合冲压成形有限元分析需要的三角形和四边形混合网格剖分算法 .按几何离散控制参数即最长边、最短边、距离误差和角度误差 ,将多裁剪参数曲面离散为多边形集 .利用曲面曲线查找裁剪参数曲面相邻关系 ,建立B Rep表示的曲面几何模型 ,并更新多边形集 .然后由多边形集得到三角形和四边形混合网格 ,结果网格单元是相容的 ,在相邻裁剪参数曲面边界处无裂缝和覆盖

Because it is difficult to mesh for a complicated assembly, this paper presents the processing method about joint relationship of complicated assembly parts, and MIXED mesh method of some typical models. This paper also meshes the example model with FREE and MIXED mesh methods on Ansys software platform. The result indicates that the number of elements meshed by MIXED is less than which by FREE, and the quality of elements meshed by MIXED is better than which by FREE. MIXED...

针对复杂装配体有限元网格划分难度大的问题,文中提出了复杂装配体中零部件的联接关系问题的处理办法及几种典型模型(腔体、薄壳体及螺钉、螺栓)的混合(切分、扫掠)网格划分方法,运用了Ansys软件对示例模型分别采用自由网格划分与混合网格划分。结果表明:混合网格划分方法比自由网格划分方法形成的单元数目更少、质量更高。混合网格划分方法可以适用于所有具有类似几何特征的模型。
