摘要
采用锰铜压力传感器法测量了约束条件和装药直径对传爆药HMX/F2641爆压的影响,传爆药密度为90%的理论密度。装药直径小于5mm时,小型化传爆序列爆压随装药直径和约束条件阻抗的减小而降低,装药直径3～5mm范围内,约束条件及装药直径对传爆药爆压的影响较小;在装药直径1.5～3mm范围内,小型化传爆序列约束条件和装药直径对传爆药爆压的影响较大。在装药密度一定时,通过装药尺寸及约束条件的匹配,可以控制并调整传爆药的爆压输出来满足不同主装药起爆的需求。
The density of the booster dynamite used is 90% of the theoretical value. When the charge diameter is less than 5.0 mm, the experimental results show that the sequence shock pressure generated by the miniaturized booster decreases following the decreasing of both the charge diameter and the restraint impedance. For charge diameter between 3.0 mm and 5.0 mm, the restraint condition and the charge diameter have less influence on the booster shock pressure than that of charge diameter between 1.5 mm and 3.0 mm. For a specified charge density, the booster shock pressure can be adjusted by properly selecting the charge shape, size and restraint condition.
