Abstract


Aiming at the problems of cracking and wrinkling in the forming process of floor beam, the design of the drawing die is finished, and the finite element analysis software DYNAFORM is used to analyze the drawing process of the floor beam, and the effects of blank holder force and drawbead on the formed part are analyzed. With the maximum thinning rate and maximum thickening rate as the evaluation index, the optimized process parameters are that blank holder force is F = 270kN and drawbead is set to segmented drawbead. The results have important reference value for the forming application of floor beam.
