板料成形中单元大小对回弹的影响研究
Study on relations of springback and mesh size in sheet metal forming
【摘要】 板料成形数值模拟的准确性在很大程度上取决于回弹模拟的精度。本文就 DYNAFORM软件中单元尺寸与回弹模拟计算的关系进行了研究 ,得出了相应的结论。
【Abstract】 The accuracy of numerical simulation in sheet matel forming depends upon the control of the springback to any great degree. In this paper,the relation of springback simulation and mesh size is studied with DYNAFORM software,and the relative results are worked out.
