Comparison and Proving of Detonation Wave of the Shaped Charge Based on Different Equation of State

为了对典型JO-9159聚能装药的爆轰波形进行分析,分别通过JWL状态方程、JWL与γ律联合方程表征JO-9159聚能装药的爆轰产物状态,计算得到了基于不同状态方程的爆轰波传播轨迹。采用高速扫描相机获得了该装药在特定位置处的爆轰波形随时间的变化规律,通过仿真与试验结果对比表明:通过JWL与γ律联合方程计算得到的爆轰波传播轨迹与试验结果更为接近,说明该方程可以更准确地描述JO-9159聚能装药的爆轰产物状态。研究结果可为聚能装药爆轰波形分析及破甲战斗部设计提供参考。

To analyze detonation wave of the JO-9159shaped charge explosive,the equation of state of JWL,and the combination equation of JWL andγwere used respectively to characterize detonation product sate of the JO-9159shaped charge explosive,and detonation wave were obtained based on the different equation of state.Variation rules between detonation wave of specific location and time was got by a high-speed scanning camera,results comparison between simulation and test shows that detonation wave calculated by the combination equation of JWL andγwas closer to the experimental results,which proves the combination equation is more accurately to describe detonation product state of the JO-9159shaped charge explosive.The research results offer references to analyzing detonation wave of shaped charge and designing of shaped charge warhead.
