摘　　要：通过有限元模拟2198铝锂合金斜面筒形件的充液拉深过程,结合试验对其塑性变形规律进行研究。研究结果表明:在板料充液拉深过程中,合适的液室溢流压力直接影响充液拉深;压边间隙影响零件的减薄率;合适的预胀压力可减小零件厚度减薄率,能够获得壁厚相对均匀,成形质量较好的零件。The process of hydrodynamic deep drawing of Al2198 was investigated by finite element（FE） simulation and experimental works. The effects of die cavity pressure, blank holder gap and pre-bulging pressure on the forming process and the thickness distribution were evaluated. The results indicate that the pressure inside the liquid chamber and the blank holder gap or blank holder force are the main factors affecting hydrodynamic deep drawing process. In addition, appropriate pre-bulging pressure is beneficial to form good quality parts with a relatively uniform wall thickness.
