Abstract：

Stamping deformation of the auto bumper was studied with Dynaform finite element analysis software combined with the actual working practice.Simulation result shows deforming rule of the parts,which is the same as the actual state.Effect of blank holding force on forming quality was analyzed through simulation.Forming quality is the best at 1100kN according to the results,which is also shown by practical application.The simulation will aid to optimize parameters and improve deforming process and product quality.It has a practical application value to supervise the production.
