| 摘 要： | 通过建立内高压成形有限元模拟模型,用MSC Marc有限元分析软件进行模拟分析,研究变径管成形过程的基本变形特征、成形参数的影响规律,探讨轴向进给与内压力的合理匹配关系. 模拟分析得知适当的提高变形速率,减少减薄区变形持续时间,有缓解该处过度减薄的作用;轴向进给应在减薄前进行补料,而不是变形同时补充所需金属. |
| 关 键 词： | 内高压成形 有限元 管材 成形参数 |

| Abstract: | By means of modeling the internal high pressure forming finite element model and simulation with finite element analysis software MSC Marc, the basic features of the shaped process and the fluence rules of forming parameters are analyzed. Simulation results show that the reduction of the duration of the deformation by increasing the deformation speed properly can decrease the thinning availably; and axial feeding should be carried out before thinning instead of during the deformation. |
| Keywords: | internal high pressure forming finite element tube component forming parameter |
