Aimed at the forming need of aluminum-magnesium alloy and other low plasticity materials, a new double loading paths process of hydrodynamic deep drawing (HDD) with independent radial hydraulic pressure and chamber pressure was brought forward. The numerical simulations of the aluminum-magnesium alloy (5A06) flat bottom cylindrical cup';s HDD with double loading paths process were carried out by employing the large non-linear dynamic explicit analytical software ETA/Dynaform5.5. The chamber pressure variations to the formability effects were discussed. The influence of different independent radial hydraulic pressure loading paths on the forming quality was analyzed by taking the wall-thickness distribution as standard. The results show that adopting the reasonable liquid chamber pressure loading curves and the independent radial hydraulic pressure from 20 MPa to 45 MPa can increase the forming limitation of aluminum-magnesium alloy cup effectively. The drawing limitation obtained is 3.1.
