Optimal Research of Process Parameters on the Springback in Sheet Metal Forming Based on Genetic Algorithm

The construction process of the springback optimization model based on the genetic algorithm has been studied .Taking the blank holder force and the clearances between the punch and the die as the optimization variable,considerlng the attenuation quantity of blank as the restriction conditlon,thinklng the certain spingback angle as the target function,by using DYNAFORM to settle the target function,the optimization models and systems about the spingback control of the blank deformation have been constructed,with the boundary pressure and the clearance between punch and die that is fit for the process requirement,whlch carries out the process parameters optimization during the blank deformation and offers an effective way to optimize the process parameters of btank deformation.
