| 摘 要： | 采用锰铜压力传感器法测试了 PMMA 约束条件下小尺寸装药输出冲击波经不同隔板后的压力, 得出了 JO-9C 传爆药爆压在不同装药直径的衰减规律和相应关系式. 研究结果表明, 小尺度装药爆轰输出冲击波经隔板衰减呈指数型规律, 衰减系数随着直径的增大而减小. 由此可知, 小尺寸装药经不同厚度隔板衰减后, 压力随之发生相应变化, 因此可以通过调整隔板厚度控制装药的爆轰性能. |
| 关 键 词： | 小尺寸装药 爆压 约束 有机隔板 衰减 |

| Abstract: | Manganese-Copper pressure method is adopted to test the different pressure when small diameter charge brings detonation pressure to bear on different PMMA gap to obtain its attenuation regularity of JO-9C booster explosive and experiential relational expressions.The results indicate that the attenuation of small diameter charge detonation pressure by using PMMA appears exponential rule,and the bigger charge diameter is,the smaller modulus decay is.With changing PMM-A thickness,the detonation pressure also c... |
| Keywords: | small diameter charge detonation pressure bound the PMMA gap attenuation |
