摘要

介绍了激光驱动飞片加载金属箔板成形的方法。采用激光驱动飞片的Gurney 模型, 计算得出功率密度0.64 GW/cm2时, 10 μm厚的铝飞片速度可达到250 m/s, 碰撞压力为1.9 GPa, 是约束模型下激光诱导压力的3倍左右。表明激光驱动飞片加载的成形能力显著高于激光直接冲击; 采用LS-DYNA软件数值模拟了激光驱动飞片加载铝箔微成形过程, 发现冲击载荷下飞片应力、速度变化的模拟结果与理论计算吻合度较好, 验证了激光驱动飞片加载机制的正确性。

Abstract

The method of metal foil forming under laser-driven flyer loading was introduced and the speed of flyer was calculated through Gurney model. The 10 μm thickness aluminum flyer reached a speed of 250 m/s when laser power density was 0.64 GW/cm2. The impact pressure went up to 1.9 GPa which was about 3 times of laser induced at constraint model. It was shown that laser driven flyer loading had higher forming ability than laser shock. The micro-forming process of metal foil under laser-driven flyer loading was simulated by LS-DYNA. The flyer stress and speed was studied, the simulation results agreed well with theoretical calculations. And the mechanism of laser driven flyer loading was verified.
