开展交感爆炸(SD)实验需要进行钝感弹药(IM)评估。爆炸碎片或强烈冲击波的撞击是交感爆炸的原因。本文提出了一种数值模拟方法来预测爆炸碎片冲击下引信爆炸列车的共鸣爆轰行为，该方法包括点火与增长(I&G)模型、Jones-Wilkins-Lee(JWL)状态方程和本构关系。将实验结果与数值计算结果进行了对比分析，验证了数值模拟方法的有效性。研究了引信在单施主和多受主作用下的共鸣起爆行为。通过数值模拟得到了碎片存在时的临界距离。建立了临界距离模型，为关联引信炸药串的起爆顺序和放置距离提供了理论模型。模拟结果与理论计算吻合较好，可以为共振爆轰实验提供支持。
Insensitive munitions (IM) assessments are required to carry out the sympathetic detonation (SD) experiments. The impact of blast fragments or strong shock waves is the cause of sympathetic detonation. In this paper, a numerical simulation method is developed to predict the sympathetic detonation behavior of fuze explosive trains under the impact of blast fragments, which includes the ignition and growth (I&G) model, the Jones-Wilkins-Lee (JWL) equations of state, and a constitutive relationship. The experimental and numerical results were compared and analyzed, and the validity of the numerical simulation method was proven. The sympathetic detonation behavior of a fuze was studied for a single donor and multiple acceptors. The critical distance was obtained with the presence of fragments using numerical simulation. A critical distance model was developed, which provides a theoretical model for relating the detonation sequence and the placement distance of the fuze explosive train. The simulated results agreed with the theoretical calculations, and thus the model can provide the support for sympathetic detonation experiments.
