摘要
研究了破爆型随进串联战斗部第一级装药爆作后对第二级弹体的影响。用中低压型50Ω锰铜计测量二级弹体上的压力历史，提出了数值计算模型，采用多流体网格方法，对爆轰产物用可变指数的多方气体状态方程，得到了第一级装药爆炸后在第二级弹体上形成的超压和冲量。数值计算结果与物理实验符合较好。
Studies through numerical simulation the effect upon the follow-through charge of the detonation in the forward charge (shaped charge) for a tandem warhead.A simplified numerical model is proposed,adopting the multi-fluid method,when perfect-gas equation of state having variable index is used for the explosive.The over-pressure is obtained along with the total momentum transmitted to the follow-through charge by the blast wave forming by the explosion in the foward charge.Results of calculation agree well with the experimental results using Mn-Cu piezoresistance gauges.
