| 目的 研究冲击载荷下炸药内部损伤随时间变化特征对其冲击感度的影响规律。方法 针对损伤状态随时间变化的两种典型情况，采用冲击波模拟加载的方式对炸药装药进行损伤实验。损伤的恢复时间很长时，在损伤后将试样放置7天后，再研究其损伤状态对其冲击起爆特性的影响；恢复时间很短时，通过控制冲击损伤实验和冲击感度实验之间的时间间隔模拟多层靶板撞击的实际情况。选择常用的两种奥克托金基炸药作为研究对象，通过冲击感度实验确定临界隔板厚度、设计损伤条件，然后进行两种不同损伤愈合时间后的冲击起爆特性实验，研究损伤状态对炸药装药冲击起爆特性的影响。结果 在文中损伤条件下，放置7天后，炸药装药的冲击感度均显著下降，而类似于侵彻多层靶板条件的实验后，炸药装药的冲击感度显著增加。结论 炸药装药损伤状态随时间的变化对炸药装药冲击起爆有完全不同的影响趋势，在相关的炸药装药安全性设计时，必须考虑与损伤时间状态相关的冲击起爆特性。 |

| Objective To research the influencing rule of internal explosive damage of shock load on shock wave sensitivity with time. Methods For damage status changing over time of two typical cases, the shock wave was used to simulate loading to inspect the damage. When the damage recovery time was very long, the damaged sample was kept for seven days before it was used to research its damage status on the shock wave sensitivity; when the recovery time was very short, the actual situation of impact between several layers of target plates were simulated by controlling the time internal between shock damage test and shock wave sensitivity. In usual, two kinds of HMX based explosives were used to determine the thickness of critical partition and the damage condition of design. Then, the impact wave sensibility was tested with two kinds of recovery duration to study the influences of damage status on impact wave sensibility of explosives. Results After being kept for 7 days in the aforementioned damage conditions, the shock wave sensitivity of explosive charging decreased apparently. While the shock wave sensitivity increased significantly after being tested in conditions similar to multi-layer target plate. Conclusion The different damage coalescence times have the different variation trend of shock wave sensitivity. The shock wave sensitivity of damaged explosive charge is time dependent. |
