| 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,结合实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,合适的液池溢流压力是关系到充液拉深能否成功；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。

| Abstract: | In this research, the process of hydrodynamic deep drawing of Al2198 was investigated by using finite element simulation experimental works. And the effects of die cavity pressure, blank holder gap and pre-bulging pressure on the forming process and the thickness distribution were analyzed. The research indicated that the pressure inside the liquid chamber and the blank holder gap or blank holder force were the main factors affecting hydrodynamic deep drawing process. And appropriate pre-bulging pressure was beneficial to form a good quality parts with a relatively uniform wall thickness. |
