| 中文摘要: |
| 分析对比了大型U形槽板的2种折弯成形方式，取U形槽板的小件进行多工步折弯回弹的有限元模拟并进行了相应的物理实验，得出了回弹角度预测值，提出在多工步折弯回弹有限元模拟中要注意的问题，为大型U形槽板的折弯成形生产提供了参考。 |
| 英文摘要: |
| Two bending styles of huge U-shaped trough plates were analysed. After the FEM simulation of multi-step bending springback was did and corresponding experiments were conducted through the small U-shaped trough plates, the predictive value of springback angle was obtained and some issues that should be payed attention to were put forward in the FEM simulation of multi-step bending springback, which provides references for huge U-shaped trough plates production |
