Abstract

The finite element model was established and the forming process of magnesium alloy sheet in radial pressure deep drawing was simulated by using the commercial FE software Dynaform. The influence of hydraulic pressure and die clearance on forming limit, wrinkle, wall thickness variations and distribution of magnesium alloy sheet were discussed respectively. The results indicate that magnesium alloy sheet showed poor deformation behaviors when the excessive hydraulic pressure (more than 25MPa) was adopted in radial pressure deep drawing. The obviously wall thickness thinning of workpieces always appeared at cylinder wall and punch corner, the maximum wall thinning was 0.103mm. Preferable wall thickness variations of AZ31B magnesium alloy can be obtained when the die clearance was increased moderately. The obtained maximum thickness thinning of AZ31B workpieces were 11.33%, 17.5% and 16% when the die clearance C were 0.66 mm, 0.6 mm and 0.56 mm.
