充液拉深是一种板料冲压成形新工艺，本文用ＭＡＲＣ软件对圆锥形零件充液拉深过程进行了数值模拟．揭示了充液拉深法的主要优点，阐明了该工艺对圆锥形零件的侧壁挠度和起皱的抑制机理．
Liquid-filled drawing is a new process of sheet metal stamping. In this paper, the numerical simulation of liquid-filled drawing of conical parts by MARC software is carried out. The main advantages of liquid-filled drawing method are revealed, and the inhibition mechanism of the side-wall deflection and wrinkling of the conical parts is clarified.
