新型高能熔铸基体炸药3，4‑二硝基吡唑（DNP）的冲击Hugoniot关系，是探讨其冲击起爆特性的基础，采用压力对比法，经平面波发生器加载，用锰铜压阻计测量了压力为3.7~14.4 GPa范围内九组不同冲击波压力下DNP炸药和LY12铝样品的冲击波波后压力，计算得到不同压力下的冲击波波速D和粒子速度u，拟合得到了压力为3.7~14.4 GPa范围内DNP炸药的D‑u关系。结果表明，DNP炸药压力为3.7~14.4 GPa范围内的冲击Hugoniot关系可近似为一条在D‑u平面内的直线，确定了DNP炸药冲击波作用下的波后状态。分析了用聚四氟乙烯封装锰铜压阻计对实验测试结果的影响，通过对测试信号的理论分析和合理判读有效消除了封装带来的系统误差。“,”3， 4‑dinitropyrazole（DNP）， a new type of smelt‑cast matrix explosive， is a kind of high energy matrix with great application potential. The impact Hugoniot relationship of explosive is the basis to investigate its impact initiation characteristics. For this reason， the pressure comparison method was adopted in this study. Plane wave generators were selected to act the designed loading. The post‑shock pressure of DNP explosive and LY12 aluminum samples under nine shock pressures were measured by manganese‑copper piezoresistivity gauges. By calculating the experimental data， the velocity （D） of the shock wave and the velocity u of the particle under different pressures were obtained. The D‑U relationship of the DNP explosive in the range of 3.7~14.4 GPa was obtained by fitting. The results showed that the Hugoniot relationship of the DNP explosive in the range of 3.7~14.4 GPa could be approximated as a straight line in the D‑U plane. The post‑wave state of DNP explosive under the action of shock wave was defined， which provided a reference for further study of impact ignition and initiation of DNP explosives. In addition， the influence of polytetrafluoroethylene packaging of manganese‑copper piezoresistance gauges on the experimental test results was analyzed. The systematic error caused by packaging was effectively eliminated through theoretical analysis and reasonable interpretation of test signals.
