摘要
基于ＣＡＤ造型理论和算法，提出了针对三维塑性有限元数值仿真中网格再划分有效的算法．基于一定的软件平台，建立了通用三维塑性有限元网格再划分系统ＲｅｍｅｓｈⅢ．最后以方坯料镦粗为例检验了系统．
Aimed at remeshing one of the kernal techniques during the threedimensional bulk metal forming FEM simulation,effective methods are put forward.Based on UnigraphicsⅡ's advanced development tools,the remeshing code Remesh Ⅲ is programmed and checked by the cubic billet upsetting.
