Virtual Debugging Technology for Automotive Mould

CHEN Yu-quan,WU Ming-yang,AN Ai-min,WANG Huan,CHEN Ze-wu(Harbin University of Science and Technology,Harbin 150080,China)  
Taking the mould design of hinge installed plates which used for trunk lid of cars as an analyzed object,a study for mould virtual debugging was carried out based on AUTOFORM.It includes Stamping forming numerical simulation and analysis,planning stamping process projects,determining technical supplementary form,and determining reasonable Stamping parameters.According to the simulated data of the thickness changes,stress-strain and FLD materials and so on,and the time,location and geometry of the rupture and wrinkling in the process of molding,the relevant parameters,such as the radius of the round comer of concave-convex die,the size of rough material,Friction,blank holding force(BHF),the size and shape of draw-beads and technique supplement and so on,were adjusted.The stamping defects are eliminated by using virtual debugging of the mould.
