| 中文摘要: |
| 首先利用有限元逆向法模拟得到一个毛坯的初始形状,然后对其进行充液成形过程数值模拟,根据成形模拟情况对其尺寸进行优化,并进行了实验验证。 结果表明,该零件合理的毛坯形状为圆形,数值模拟和实验结果符合较好。 |
| 英文摘要: |
| Finite element increment method and finite element inverse method are adopted. One initial blank shape was obtained by the inverse finite element method firstly. And then the hydroforming process was simulated. The blank shape and size were optimized. The experiment was carried out finally. The results have shown that the optimized blank shape is round. The results of simulation keep a good agreement with the experiment results. |
