| الوصف: | One of the most relevant research issues in automotive field is focused on the reduction of stamped partsweight also increasing their strength. In this way, a strong research effort is developed on high strength steels which arewidely utilized and they require a proper springback control. Springback reduction in sheet metal forming is a typicalgoal to be pursued which is conflicting with thinning reduction for instance. Thus, such problems can be considered asmulti-objective ones characterized by conflicting objectives. What is more, nowadays, a great interest would be focusedon the availability of a cluster of possible optimal solutions instead of a single one, particularly in an industrialenvironment. In this paper, integration between numerical simulations, response surface methodology and Paretooptimal solutions search techniques was applied in order to design a DP 600 U-channel shape stamping operation. Inparticular the friction conditions and blank holder force were optimized as design variables in order to accomplish twodifferent objectives: reduce excessive thinning and avoid excessive geometrical distortions due to springbackoccurrence. |
