Simulation Results

Numerical simulation is an effective method for predicting formability of metals, and the use of computer simulation enables a significant increase in the number of tool designs that can be tested before hard tools are manufactured. Based on dynamic explicit finite element software, finite element simulation of sheet metal forming was performed to investigate the applicability of applying hydrostatic pressure on blank in multi point discrete dies. Simulation results show that using the hydrostatic pressure on blank is apposite for the process of multi point discrete dies.

Cae Simulation

The features and functions of Autoform software for sheet metal forming simulation were introduced. Taking the auto panel as an example, based on UG and Autoform, the process of CAE simulation analysis on the drawing process was stated in this paper and the simulation results were analyzed. The results of analyses indicated that the crack tendency was in the two salient of auto panel flange in the drawing process. By optimizing and adjusting the parameters of mold, the problem of crack tendency was solved. The optimal stamping process was finally determined based on the results of the simulation. Compared with the traditional stamping technology and die designing, the quality of die designing was improved by adopting CAE technique.

The multi-step forward finite element method is presented for the numerical simulation of multi-step sheet metal forming. The traditional constitutive relationship is modified according to the multi-step forming processes, and double spreading plane based mapping method is used to obtain the initial solutions of the intermediate configurations. To verify the multi-step forward FEM, the two-step simulation of a stepped box deep-drawing part is carried out as it is in the experiment. The comparison with the results of the incremental FEM and test shows that the multi-step forward FEM is efficient for the numerical simulation of multi-step sheet metal forming processes.
