摘要(Abstract):
基于AUTODYN软件建立了水下爆炸一维楔形模型,对空气不耦合装药结构下爆炸能量的输出进行研究。首先获得炸药冲击波压力以及气泡脉动随时间的变化曲线,进一步获知径向不耦合状态下水下爆炸的冲击波峰值压力、气泡最大半径以及脉动周期等数据,并最终得到了不耦合系数下冲击波能以及气泡能的变化情况。将计算结果与已有的水下爆炸实验结果进行了比较分析。结果表明,该计算结果与实验数据吻合较好,证明了利用数值计算手段可以实现定量化表征炸药输出能量随不耦合装药结构的变化规律。
A one-dimensional wedge model of underwater explosion is established in this paper based on AUTODYN to study the air decoupling charge.The shock wave pressure verse time curve and the bubble pulsation verse time curve are recorded.The characteristic parameters peak pressure,the first gas buddle pulsation period and radius are further obtained.Finally,the relationship between shock wave energy,bubble energy,total energy and the decoupling coefficient is gotten.The calculated results are compared with the existing experimental results.The results show that the calculation is in good agreement with the experimental data.It is proved that the variation of output energy with decoupling charge structure can be quantitatively characterized using the numerical method.
