| 摘 要： | 针对高速钻地弹侵彻过程的装药损伤所引起的炸药不安全问题,采用装药缩比弹侵彻试验后回收内装药样品的方法,观测分析某新型炸药装药侵彻后的外观和密度变化,并通过损伤样品的冲击起爆隔板试验,测试其临界隔板厚度变化,进一步研究侵彻过程冲击载荷对装药损伤的影响.试验结果表明,弹体不同位置的装药损伤程度不同,其中弹体头部和尾部装药损伤明显,中部装药损伤相对较轻;且装药损伤程度随侵彻速度增大而增大,冲击起爆感度提高也越趋明显. |

| Abstract: | With respect to the explosive charge unsafety caused by high-speed earth penetrator,the penetration test was carried out with subscale projectiles,and the test projectiles were recovered to check the variations of appearance and density of explosive charges.Baffle test was also performed to test the thickness variations of critical baffle and the effects of the impact loads on the damaged to explosive charge in the process of penetration were studied further.Results show that the damages to the explosive ch... |
