Abstract：

The effect of different drawing speeds on deep drawing limit factor of dual-phase steel B340/590DP sheet was studied by numerical simulation and drawing experiment.Numerical simulation shows that the thickness reduction rate of 0.8 mm sheet metal increases from 11.473% to 16.638% when the stamping speed increases from 10 mm·s-1 to 60 mm·s-1. Drawing experiment results with the same set show that crack happens easily when stamping speed is greater than 60 mm·s-1, forming limit parameters of the finite element model and the actual drawing experiments data have a good consistency. Under the drawing mode which the slider motion velocity trajectory is controlled, raising stamping speed when drawing depth is larger than 10 mm can reduce the cracking, wrinkling and other defects. Reasonable setting of initial and subsequent forming speeds can increase the limit speed of drawing and improve the efficiency.
