用有限差分法（FDM）模拟了圆杯拉深和重画过程中的金属流动。使用1100-0和3104-H19铝合金在多作用ERC/NSM压力机上进行了实验。在这些实验中，测量了力和应变，并与模拟结果进行了比较。研究了润滑、拉伸比等工艺参数对拉伸杯质量的影响。

THE METAL FLOW IN DEEP DRAWING AND REDRAWING OF ROUND CUPS HAS BEEN SIMULATED USING THE FINITE DIFFERENCE METHOD (FDM). EXPERIMENTS HAVE BEEN PERFORMED IN THE MULTI-ACTION ERC/NSM PRESS USING ALUMINUM ALLOYS 1100-0 AND 3104-H19. IN THESE EXPERIMENTS, FORCES AND STRAINS WERE MEASURED AND COMPARED WITH THE SIMULATION RESULTS. THE EFFECT OF PROCESS PARAMETERS, SUCH AS LUBRICATION, AND DRAW RATIO, ON THE QUALITY OF DRAWN CUPS HAS BEEN INVESTIGATED.
