Numerical Simulation and Prediction of Springback in Bending Process for Bimetal Bushes
Plastic processing accuracy of large-scale bimetal bushes is tough to get accurate prediction and control.To solve this problem,two-dimensional elastic-plastic finite element models were established based on the finite element MSC.Marc platform.The bending process of bimetal bushes was simulated.The deformation characteristics of the bimetal billet during the process was researched and values of springback were further obtained in unloading stage.
