为探索不同间距两个相同质量炸药在无限空域中同时起爆形成的爆炸威力场特性
借助有限元仿真软件
通过建立不同间距的两点炸药在自由场空中爆炸的数值模型对两点阵列爆炸进行数值研究
获取计算域各空间点的冲击波参数
分别绘制了基于超压和冲量准则的等毁伤区域轮廓线
并对等值面的几何特性随间距的变化规律进行研究。研究结果表明:压力增强效应和多峰效应是爆炸威力场重构的主要原因;两点爆炸威力场的等毁伤区域随分离距离增大呈现3种典型形状;与单点爆炸相比
两点爆炸威力场的体积和特定方向的覆盖范围仅在部分分离距离范围内有增益
增益大小与分离距离和准则阈值有关;作为阵列爆炸中最为基础的作用形式
两点爆炸的相关研究结论可以为多点阵列爆炸威力场特性研究和多弹协同作战模式设计提供参考。
In order to explore the characteristics of explosive power field formed by simultaneously detonated two explosives with different spatial intervals in infinite air space
a numerical model of two-point explosives with different spacing distances in free field air explosion is established to numerically study the two-point array explosion. The shock wave parameters of each space point in the calculation domain are obtained
and the contours of equal damage region based on overpressure and impulse criteria are drawn
respectively. The geometric characteristics of iso-surface with the change of space distance are studied. Results show that the pressure enhancement effect and multi-peak effect are the main reasons for the reconstruction of explosive power field. With the increase of the separation distance
the equal damage region of two-point explosion field presents three typical shapes. Compared with single point explosion
the volume of two-point explosion power field and the coverage area in specific direction only have gains in the range of partial separation distance. The relevant research conclusions related to the separation distance and criterion threshold can provide a reference for the study of multi-point array explosion power field characteristics and the design of multi-bomb cooperative combat mode. As the most basic mode of array explosion
these results can provide a reference for the study of multi-point array explosion power field characteristics and the design of multi-bomb cooperative combat mode.

DOI: 10.1016/j.dt.2021.05.020 http://doi.org/10.1016/j.dt.2021.05.020 In this study, we focused on the effect of the underwater explosion parameters of multi-point array explosion. The shock wave and bubble parameters of aggregate charge, two charges, and four charges were measured through an underwater explosion test, and their influence on the explosion power field of charge quantity and array distance was analyzed. Results show that the multi-shock wave collision of array explosion can be approximated to a linear superposition, and the interaction of delayed shock wave can be deemed as the increase of the shock wave baseline. Shock wave focusing and delayed superposition increase the shock wave peak pressure. Compared with the aggregate charge, the greater the number of array explosion points is, the higher the impulse and the gain of the bubble peak pressure are. At the same array distance, the smaller the charge quantity is, the higher the bubble impulse will be. At the same charge quantity, the smaller the array distance is, the higher the bubble impulse will be. The bubble period decreases gradually with the increase of the charge quantity, but the test orientation has little effect on the bubble period. © 2021 China Ordnance Society
