Study and evaluation of different formaulations of the optimization problem applied to the stamping process

摘要

Th application of optimization algorkthms to the numerical simulation of stamping process is due to the low computational cost obtained with software based on an inverse approach. However, the definitiion of the optimization problem is difficult because several objective must be satisfied simultaeously. The formulation that we propose in this paper allows to separate the feasibility critieria from the quality criteria, and to simplify the formulation of the multi-criteria problem. We, also compare several methods to solve the optimization problem and show the advantages of the methods based on sensitivity analysis.
