| 摘 要： | 针对CAE工程分析中网格模型的特点,提出了一种符合CAE特点的网格模型特征重建方法。鉴于CAD模型中的设计细节在CAE分析中可以忽略的特点,对CAD模型中的小圆角、倒角、小凸台等非结构性设计特征,采用基于面片法矢迭代滤波方法进行识别和滤除。算法首先识别出这些特征区域,然后根据非特征区域面片法矢调整特征区域法矢并更新顶点坐标,进行特征重建,最终得到符合CAE要求的网格模型。

| Abstract: | Based on the analysis of CAE used mesh model,this paper puts forward an algorithm of the characteristics of CAE method mesh features.In view of the design details of the CAD model can be ignored in the CAE analysis of the characteristics of CAD models in this paper,a small fillet,chamfer,roller and other non-structural design features,vector-based Facet iterative filtering method was used to identified and removed.Firstly,identify the characteristics of the region,and then non-characteristic area under the ... |
