| 摘 要： | 利用锰铜压阻传感器法测量了某聚奥传爆药在不同直径下的小尺寸装药爆轰输出冲击波经不同厚度有机玻璃隔板衰减后的冲击波压力,通过对实验数据进行拟合,得到了有机玻璃介质中冲击波衰减系数与装药直径的指数型关系.实验中传爆药装药密度为90%的理论密度,约束条件分45#钢和有机玻璃两种,装药直径为1.5 mm、3 mm、5 mm和8 mm.结果表明: 衰减系数随装药直径增大而减小,装药的约束条件越弱,这种变化越明显. |

| Abstract: | The output shock wave pressure attenuated by different thicknesses of PMMA gaps of booster JO with small size charge diameter was measured by manganin piezoresistance method. The exponential regularity of the shock wave attenuation coefficient versus the charge diameter in PMMA was obtained by fitting experimental data. The load density of the booster was 90% of the theoretical density, and the charge diameter was 1.5 mm, 3 mm, 5 mm and 8 mm with confinement of 45# steel and PMMA. Results show that the attenuation coefficient tends to decrease with the increasing of the charge diameter under the same confinement. The confinement of the charge is stronger,the change is more obvious. |
| Keywords: | military chemistry and pyrotechnics shock wave attenuation small size charge shock wave pressure manganin piezoresistance method |
