摘要
对1kg柱形某含铝炸药进行了水下5m的水池爆炸实验,并基于AUTODYN软件模拟了含铝炸药水下爆炸冲击波与气泡脉动规律,研究了非理想爆轰对冲击波与气泡特性的影响.模拟研究表明,Miller能量释放模型能够准确地反映含铝炸药的非理想爆轰过程,可准确模拟出冲击波后期压力值、气泡二次压力以及气泡的周期与半径,计算值与实验值具有较好的一致性.以此为基础研究了装药参数及起爆方式对近场冲击波压力峰值的影响,有限元模型、方法以及计算结果对相关研究和计算具有一定的参考价值.
Underwater explosion of aluminized explosive and its character were simulated by using AUTODYN software.Effect of non-ideal detonation on shock wave and bubble pulsation was investigated numerically.The aluminized explosive of cylindrical charge with a weight of 1 kg was detonated underwater at a depth of 5 m in an explosion test tank.The numerical results show that the Miller model could precisely simulate the phenomenon of the shock wave and bubble pulses and the simulation data could be consistent with the experimental data.Moreover,the effect of charge parameters and detonation mode on the peak pressure of shock wave has been analyzed and summarized.This work has a certain value to the calculation and simulation for further research.
