Optimum die deisgn for sheet metal formign process by using finite element and idscretized optimization mehtods

摘要

The optimum die design system was developed by combining finite elemetn (FE) analysis and discretized optimization alogorithms.THis ocmputerized die design systme is represied in industries to reduce time ocnsumption and cost.Recently,advanced FE analysis has porvided accurate forming-process informaiton.However,the synthesis technolgy to determine the optimum forming-process condition,which inlcudes optimum die design,is still insufficient.
