激光驱动飞片冲击引爆炸药的计算
-
摘要: 在Gurney方程和考虑金属相变状态方程的基础上， 提出了一种激光驱动飞片运动的计算模型。这种模型能确定与炸药临界起爆相关的参数，诸如沉积的激光能量、烧蚀层和飞片的厚度以及飞片飞行的距离等等。计算的结果与实验相符。在本模型中可以对电离、烧蚀及二维效应作进一步的考虑。Abstract: On the basis of Gurney equation and the equation of state considering phase transition for metals, a model to calculate the movement of the laser driven flyer is proposed in this paper.This model can be used to determine parameters related with critical initiation of explosive, such as deposited laser energy, thickness of ablation layer and flyer, flying distance and so on. The calculated results are consistent with the experiments. Further considerations of ionization, ablation and two dimensional effects are possible to be included in the model.
