| 摘 要： | 在激光冲击波加载转换模型的基础上，以有限元分析软件ABAQUS／CAE为平台，对圆形板料进行了直线形轨迹和圆形轨迹多点冲击成形的数值模拟，探索了冲击轨迹、应力分布和板料变形之间的相互关系。数值模拟分析表明，对圆形板料进行多点冲击成形时，选择圆形轨迹是最佳的。根据模拟结果对铝合金板料试样进行了无间隔冲击成形的实验，获得了和数值模拟相同的成形结果，模拟和实验结果一致性较好。

| Abstract: | Laser shock forming (LSF) is a novel technique that uses laser-induced shock wave to shape sheet metal. The principle of sheet metal forming caused by multi-shock laser shocking was investigated. On the basis of mathematical modeling of laser shock loading, numerical simulation of deforming process of sheet metal was done with the ABAQUS code along the tracks of linear and circular pattern. The relationship between the main parameters of laser shocking and the deformation of sheet metal was studied, and the optimized track was obtained for the deformed sheet of round shape from the numerical simulation. According to the simulation results, the experiment of overlapped laser shock forming of aluminum alloy specimen was carried out and the obtained deformation of sheet metal was in agreement with the simulations analysis. By means of FEM technique, the laser process parameters can be optimized and the deformation contour of LSF of sheet metal can be predicted. |
