[0138] Example 1
[0139] A multi-objective optimization method based on the fusion of Dynaform and intelligent algorithms, including the following steps:
[0140] (1) Numerical simulation of stamping forming process: establish a computer-aided design model, and use finite element analysis software Dynaform to carry out stamping forming numerical simulation, map the physical process of stamping forming, establish a finite element network in Dynaform, and divide the network;
[0141] (2) With the help of the Dynaform mesh repair ModelCheck / Repair tool, the part boundary and the actual margin are compared and checked, the Overlap tool is used to check the overlapping element, and the CursorPickPart tool is used to check the normal direction of the element. Through the punch and sheet drawing process, Obtain the finite element model of the sheet metal stamping process;
[0142] (3) Orthogonal experimental design: select five parameters: stamping speed, friction coefficient, blank holder ...
