Drawing experimental and simulation research on flexible sand die for magnesium alloy covering parts based on three driving modes
Sand was selected as the flexible medium,different driving modes were realized by the different placement of sand,and complex magnesium alloy covering parts were studied.Finite ele-ment simulation and rawing experiment were compared and verified,the influences of drawing temperature,sheet thickness,and sand filling height on the forming results of magnesium alloy sheets were investigated.The finite element simulation was verified by the method of macroscopic and microscopic cooperative verification.Finally,the optimization strategy to improve the drawing performance of complex magnesium alloy covering parts was proposed.
