| 摘 要： | 实验研究了激光能量和不同的冲击路径、冲击次数对TA2钛合金板料变形的影响，并用ABAQUS软件进行了有限元模拟。结果表明：随着激光能量的增加，板料的变形量增大；板料几何尺寸和厚度越大，板料越难变形；冲击次序不同，板的变形量也不同，板的变形以沿板的长度方向且对称冲击为最大。通过数值模拟可优化激光冲击的相关参数，预测板料变形。

| Abstract: | The basic principle of laser shock forming was described and the influences of some factors on the deformation results of TA2 sheet were simulated by ABAQUS. The results indicate that the deformation of TA2 sheet metal increases with increase of the laser energy and varies with shock orders and will be the greatest when shock is along the length of plate and symmetrical. |
