N2 - Viscous pressure forming(VPF) using a semi-solid, flowable, highly viscous and certain rate sensitive macromolecule polymer as the forming flexible-die is a good forming method for high strength, low plasticity, complex sheet metal parts. In this paper, the bulging process of aluminum alloy 2024 sheet is carried out by combining methods of experiments with numerical simulation. Influences of viscous medium properties on the geometry of bulging specimens, thickness distribution and the pressure field of viscous medium are analyzed, and the limit bulging heights of aluminum alloy 2024 sheets are obtained. The research results show that choosing viscous medium with high rate sensitivity in the forming process can increase the non-uniformity of viscous pressure field, improve the viscous pressure bulging property of aluminum alloy 2024 sheet, and ameliorate the distribution uniformity of wall thickness of bulging specimens.
