Abstract：

Based on eta/Dynaform, the drawing process of upper beam in rear body was numerically simulated. The relationship among plastic deformation of upper beam in rear body, loading modes and velocity during drawing process was studied. When the drawing velocity of steel plate changes from large to small，the drawing formability of the part is good. By servo technology，the movement curves of drawing were optimized，which improved the drawing formability through changing the movement locus of drawing process. The simulation met with the physical experimental result，and qualified stamping parts were obtained by both experiments.
