数值模拟参数和工艺参数对板材成形回弹影响的研究

Research on the influence of process and simulation parameters on springback in sheet forming process

应用PAMSTAMP模拟软件研究分析了影响回弹计算精度的因素 ,包括网格尺寸、虚拟冲压速度和自适应网格应用 ,及工艺参数对回弹量的影响 ,包括压边力。

The factors influencing on the accuracy of springback calculation,including average mesh size,punch velocity and usage of adaptive mesh refinement,and the factors influencing on springback in sheet forming process,including blankholder force,material properties and friction coefficient,are studied with PAMSTAMP softwere in this paper.
