| 摘 要： | 提出利用激光冲击波技术实现板料的柔性塑性成形，分析了其成形机理、工艺过程和技术特点。利用脉冲能量为10－30J，脉宽为20ns的激光束，对SUS304薄钢板和40Cr进行了激光冲激波胀形实验，初步的实验结果表明，激光冲击波板料成形是一种冷塑性成形技术，具有超快速、高应变率等优点和较大的成形柔性。能适用于常规模具无法成形的结构钢和复合材料的成形，拓展了冷冲压成形的零件范围。

| Abstract: | A new technique about flexible plastic forming of sheet metal by laser shock waves is presented for the first time , the mechanism and process of laser shock forming(LSF) is studied. The initial forming exploration is carried out through bulge testing with specimen SUS 304 and 40Cr sheet metal ,using a neodymium-glass laser of pulse energy 10~30J and FWHM 20ns. The investigation revealed the LSF is characterized as super speed and ultra-high strain rate, and may be fit to form the sheet of structure steel and composite materials with or without a mould. |
