摘要
为了研究反应装甲对射流的切割和干扰作用,开展了射流对薄钢板穿孔规律的研究。借用半无限靶的开坑模型,应用流体力学的方法加以修正,通过实验验证,可以用来计算薄钢板刚被穿透时的孔径,分析高速射流对薄板的扩孔过程,计算结果在射流高速段和成孔的初期阶段与实验结果吻合较好。
For researching the effect of breaking and disturbing of explosive reactive armors to jet ,study on the rule of the penetration of the jet against thin steel plate. The model of the penetration of jet against semi-infinite plate was cited, which was modified by fluid dynamics method and was verified by experiment, may apply to calculate the radius of penetration hollow while thin steel plate was penetrated just now, and to analyze crater growth course of high velocity jet to thin plate. The results of computations of the initial penetration of jet demonstrated good agreement with experiment.
