摘　　要：金属板料激光成形技术是近年来出现的一种先进柔性加工技术。分别介绍了激光热应力成形、激光冲击成形(LSF)和激光喷丸成形(LPF)的成形机理,分析了成形的主要影响因素。影响这三种激光成形方式的因素主要有:激光参数、扫描轨迹、材料性质、板料几何参数和约束边界条件等。分别从机理、工艺参数、成形工艺等方面分析了这三种板料激光成形的技术特点。最后,对这三种激光板料成形技术的应用前景进行了展望,并指出激光板料成形技术在成形的精确控制及成形复杂件方面存在的一些尚待解决的关键问题。Laser forming technology of sheet-metal is an advanced and flexible precision finishing technology that is emerging in recent years. At present, sheet-metal forming by using laser techniques could be classified as laser thermal-stress forming, laser shock forming （LSF） and laser peening forming （LPF）.It introduces and analyses the forming mechanisms, main process influencing factors and technologic characteristics respecth, ely about the applications of the three laser sheet-metal forming methods which are mentioned above. At last, the application prospects of the three laser sheet-metal forming technologies are presented, and some key problems in complex products and accurate control forming, which need to be solved urgently, are also pointed out.
