介绍了深锥形杯的多道次激光冲击成形方法。采用有限元方法对三步激光冲击成形（TSLSF）过程进行了模拟，分析了板料在各步的变形过程。重点讨论了板料的变形行为，包括变形速度、应变、残余应力和几何形状。通过板料成形实验对模拟结果进行了验证。对各步成形板料形状的数值预测值与相应的实验成形值进行了比较和讨论。实验结果表明，TSLSF可以制备出三种几何形状的杯体。实验结果与相应的数值预测数据吻合较好，验证了所建立的板料成形预测模型的正确性。同时也表明，当平板需要成形为深成形件时，多道次激光选区成形是一种可行的成形工艺。
This paper presents the method to shape a deep conical cup with multi-step laser shocking forming. Finite element method was employed to simulate the process of three-step laser shocking forming (TSLSF), and the process of sheet deformation at each step was analyzed. Especially, sheet deformation behaviors including deforming velocity, strain, residual stress, and geometrical shape were discussed in detail. The sheet-forming experiments were carried out to validate the simulation results. The numerical predictions of the deformed sheet shape in each step were compared and discussed with the corresponding experimental forming values. The experimental results display that three geometrical cups have been fabricated by TSLSF. The experimental results are well accordance with the corresponding numerical predicted data, which validates the established prediction model of sheet forming. It also indicates that MSLSF is a feasible forming process when the flat sheet needs to be formed into a deep-depth workpiece.
