| 摘 要： | 本文用大变形弹塑性有限元法对金属板材柔性成形新工艺——激光弯曲进行了动态数值模拟。从热力学的观点出发，阐明了该工艺的变形机理；论证了板材厚度和光束移动速度对温度梯度和弯曲角度的影响，为该工艺进一步深入研究奠定了基础。模拟结果与试验吻合较好。

| Abstract: | New flexible forming technique of sheet metal -- Laser bending process has been numerically simulated by using finite element method of large elastic-plastic deformation in this paper. Relationship between bending angle and geometric of sheet and technology parameter is discussed. It is shown that the calculated values are in good accordance with the experiments. |
