摘要
为确定主辅装药的选型原则,对主装药在两种辅装药滑移爆轰作用下的动态响应过程进行了数值仿真研究,着重考察了辅装药爆轰性能和主辅装药间的隔爆层对冲击波衰减的影响,并结合非均质炸药的冲击起爆临界能量判据,得到传入主装药内的脉冲压力和脉冲持续时间。结果表明,引起主装药殉爆的主要因素是主装药的爆轰感度和辅装药的爆轰压力,隔爆层位置应位于辅装药和外壳体之间。
In order to obtain the principles of selecting main charge and deforming charge, the numerical simulations of the response process of the main charge under the sliding detonation of two deforming charges are studied. Combining the shock initiation criterion of heterogeneous explosive, the effect of the detonation properties of the deforming charge and attenuation layer between the main charge and deforming charge on shock-wave attenuation is discussed. The shock pressure and pulse duration propagating into the main charge are obtained. The results show that the properties of the main charge and the shock-wave pressure of the deforming charge are the primary factors of causing the sympathetic detonation of the main charge, and the attenuation layer for the main charge is better to locate between the outer case and the deforming charge.
