摘要
利用锰铜压力传感器和测时仪测量了不同装药密度和尺寸下的RDX基含铝炸药的爆压和爆速,拟合出了爆压、爆速与装药密度的关系式,研究了装药密度和尺寸对RDX基含铝炸药爆压、爆速的影响。结果表明,随着密度的增加,RDX基含铝炸药的爆压和爆速均增加;当装药直径和装药长度分别达到20 mm和40 mm时,RDX基含铝炸药已经达到稳定爆轰,装药直径和装药长度再增加,爆压和爆速基本不变。
Detonation pressure and detonation velocity of RDX-based aluminized explosive with different charge densities and charge sizes were measured by using manganin pressure transducers and probes,respectively. The relationship between detonation pressure and charge density,as well as the relationship between detonation velocity and charge density,were fitted, and then the effects of charge density and charge size on detonation pressure or detonation velocity of RDX-based aluminized explosive were analyzed. The results show that the detonation pressure and detonation velocity are both increasing with the increasing of charge density. When the charge diameter is 20 mm and. the charge length is 40 mm,RDX-based aluminized explosive is already at steady detonation,and the charge diameter and the charge length do not affect the measurement of detonation pressure and detonation velocity.
