摘要 为了研究中空激光参量对金属板料变形的影响,采用数值仿真的方法,选用不同的中空激光参量对3003铝合金板料进行了冲击成形数值模拟,分析了板料变形的动态响应过程以及成形规律。结果表明,中空激光加载后,板料获得初速度,光斑区域的速度逐渐减少,区域外的速度逐渐增加,带动整个板材的运动;与实心激光冲击板料变形比较,板料底部变形区较为平坦,变形比较均匀,提高了板料的成形性和成形极限。该研究通过选择不同的中空激光参量获得板料的成形规律,为中空激光冲击成形技术提供了依据。 In order to study the effects of hollow laser parameters on the sheet metal deformation, the dynamic response process and the deformation law of sheet metal deformation were analyzed with 3003 aluminum alloy sheet shocked under different laser parameters. The results show that, the sheet metal obtain initial velocity by hollow laser shock, the velocity of sheet metal in the spot region gradually reduces and the velocity of sheet metal outside the spot region increases, the movement of the entire plate is driven ; Compared with the deformation of sheet metal by solid laser shock, the deformation zone is relatively flat and well, the forming performance and the forming limit of sheet metal are improved. The forming law of sheet metal can be obtained by selecting different hollow laser parameters, providing a basis for the study about hollow laser shock forming technique.
