Numerical and Experimental Investigation into the Aluminum Alloy Irregular Box Sheet Hydroforming Process
Sheet hydroforming process of one irregular box with unequal height and flat bottom was investigated by numerical simulation and experiment. The effect of blank shape and pressure loading path on the forming result was discussed. The key process parameter was optimized. The results have shown that the round blank is the best shape blank. The part can be formed with the appropriate blank shape and die cavity pressure.
