摘　　要：为准确评估高速破片撞击下弹药装药的反应等级,基于高速破片加载装置,利用光子多普勒测速仪(PDV)、高速摄影、冲击波超压、自短路电探针等测试技术,以一种HMX基装药(PBX-8)为试验对象,结合静爆试验,对不同撞击条件下的装药反应等级进行了试验研究。结果表明,无反应等级与燃烧等级评估以装药反应过程宏观图像及剩余残骸情况为主进行定性评估,对于爆燃、爆炸与爆轰等级,可采用基于冲击波超压、壳体膨胀速度及反应时间等量化参量获得的反应烈度量化值进行准确评估,其中爆燃与爆炸反应等级反应烈度量化值存在量级差异。在相同的撞击速度条件下,破片撞击弹药装药位置的不同可影响装药的最终反应烈度。In order to accurately evaluate the reaction level of ammunition charge under the impact of high-speed fragments,with the help of an overloading setup,the photon Doppler velocimeter(PDV),high-speed photography,shock wave overpressure measurements,self-short-circuit electric probes,together with static explosion tests,were used to study the response levels of the HMX-based charge(PBX-8)under different impact conditions caused by high speed fragments.The results indicate that the qualitative evaluation of the non-reaction level and combustion level was mainly based on the remaining debris and the high-speed images of the reaction process.For the accurate evaluation of deflagration,explosion,and detonation levels,the quantitative values of reaction intensity were obtained from quantitative parameters such as shock wave overpressure,shell expansion velocity,and reaction time,etc.The quantification of the reaction intensity between the deflagration and explosion reaction levels exists a one order of magnitude difference.Moreover,the different impact positions of fragments on the charge can affect the final reaction intensity of the charge under the same impact velocity.
