Optimize the press processing conditions to improve wrinkle height and strain.
Press processing is a method used in the manufacturing of various industrial products, including automobiles. Since this press processing is often used for mass-produced products, it is desirable to thoroughly examine the processing conditions in advance using CAE. In this case, we optimized the processing conditions by linking the general parameter optimization software "AMDESS" with the explicit dynamic analysis software "Abaqus/Explicit Student Edition" (from SIMULIA, USA). We added recommended points based on the density of the data points we had previously investigated! We devised a way to avoid falling into local solutions. As a result, we achieved a maximum equivalent plastic strain reduction of 9% while satisfying all constraints.
