Springback Prediction of Axial Symmetry Sheet Part Drawing

Abstract:

Springback in drawing of an axial symmetry sheet metal part was studied. First of all, according to a springback formula of simple bending, the moment was modified by concerning of axial symmetry shape of part to construct a formula for predicting the springback. Then, springback process was analyzed with FE software Dynaform. Finally, drawing experiment was carried out. Use the reverse engineering and software Geomagic to obtain the shape and springback of the part. Excluding errors of measurement and simulation, the results of experiment and finite element simulation and predictive model were compared, and it shows that the predictive model works well.
