摘要
利用非线性动力学分析软件AUTODYN-2D对玻璃射流冲击起爆带壳B炸药进行了仿真研究,研究了不同装药参数对带壳装药冲击起爆的影响,实现了玻璃射流对带壳B炸药的穿而不爆。仿真结果表明,射流u2d值随着药型罩壁厚和锥角的增大逐渐减小,随着装药长径比的增大逐渐减小;玻璃射流冲击起爆带壳B炸药的u2d阀值均在15.543 mm3/μs2左右,说明玻璃射流可以用于反爆炸式反应装甲战斗部。
In order to eliminate the interference of the reaction armor to the main jet,to achieve the glass jet on the shell with the penetration-but-not-detonated,numerical simulations by AUTODYN-2 D software was carried out to emulate that glass jet initiate B explosive with shell. The effect of different charge parameters on the impact initiation of shell loading was studied,and the effect of glass jet on the shell B explosive was realized. The results indicate that the u^2d decreases as the thickness and taper angle of liner increases,but the value of the jet u^2d decreases as the charge-to-length ratio increases. The initiating value u^2d of glass jet to B explosive with shell is about 15. 543 mm^3/μs^2. The results show that glass jets can be used for Anti-Explosive Reaction Armor warhead.
