Design of the Parametric Simulation Program for Multi-Point Forming Based on APDL
Two difficulties exist in the finite element analysis of multi-point forming: the complicated modeling process and the difficulty to control the movement pattern of more punches simultaneously. In the present paper, the design process of parametric simulation program for multi-point die forming and force-displacement separated control forming by using ANSYS parametric design language (APDL) is described. The rapid modeling is realized by use of the parameter input dialog box. The calculation program for the original position of each punch is designed, and then the stroke of each punch is determined. The process of model definition, loading and analysis is controlled by customized multi-point forming toolbar. The parametric finite element analysis process for spherical surface forming with the force-displacement separated control forming method is described in the paper. The results indicate that the simulation requirements for different parameters and different forming modes can be satisfied by the designed parametric simulation program.
