摘要:
为揭示新型熔铸载体3,4-二硝基吡唑（DNP）的爆轰传播特性，建立了圆柱装药二维轴对称数值计算模型，使用标定的点火增长反应速率方程(I & G)模型对DNP炸药爆轰波传播过程进行了数值模拟，并采用连续导线法测量了DNP熔铸炸药的临界直径。结果表明：计算得到DNP炸药的临界直径为8.20 mm，实验测得DNP炸药的临界直径为7.88 mm；计算值与实验值吻合较好。通过实验与数值模拟相结合的方式对DNP熔铸炸药临界直径的研究，为DNP炸药的配方设计和战斗部结构设计提供了数据支撑。
Abstract:
In order to reveal the detonation propagation characteristics of the new melt-cast matrix 3, 4dinitrophyrazole (DNP), a two-dimensional axisymmetric numerical calculation model of cylindrical charges was established. The propagation process of the detonation wave of DNP explosive was numerically simulated using calibrated parameters of the ignition-growth reaction rate equation. Additionally, the critical diameter of DNP melted explosive was measured using the continuous wire method. The results show that the calculated critical diameter of DNP explosive is 8.20 mm, and the measured critical diameter of DNP explosive is 7.88 mm. The calculated values are in good agreement with the experimental values. By combining experiments with numerical simulations, the critical diameter of DNP melt-cast explosives can be studied, which can provide reference for the formulation design and warhead structure design of DNP explosives.
