摘要
分析和论述了板料成形有限元模拟中网格重划技术,研究并建立了板料成形有限元网格重划算法,实现了状态参量在新旧网格中的传递,结合DYNAFORM有限元分析软件,对NUMISHEET’93设定的方盒标准考题进行了模拟,结果证实了该技术的可行性。
The remeshing technique on sheet metal forming FEM has been analyzed and discussed and the high precision remeshing algorithm for sheet metal forming FEM has been built,realizing the state variable transformation between the old meshes and new meshes.Combining with DYNAFORM software,numerical simulation has accomplished on standard tests of box stipulated by NUMISHEET'93,resulting in verification of the feasibility of such technique.
