| 摘 要： | 由于铝合金的锻造温度范围很窄，金属热锻过程中温度和变形又存在显著的相互影响，所以必须结合塑性变形流动和热效应来分析铝合金热锻成形过程。运用热力耦合刚粘性有限元对铝合金热锻成形进行数值模拟，可以优化工艺参数和预测可能出现的缺陷。

| Abstract: | ue to the limited small range of aluminum alloy's forging temperature,and the large interaction between temperature and deformation during the forging process,we must use the plastic deformation together with heat effection to analyze the forging process for aluminum alloy.Using the rigid visco-plastic Finite Element Method can optimize the technological parameter and forecast the defection. |

| Keywords: | coupled thermo-mechanical plastic FEM hot forging numerical simulation |
