【摘要】 为研究黑索今(RDX)炸药单晶的冲击起爆性能,采用奥克托今(HMX)基炸药直接起爆单晶的方式,并用任意反射面激光位移干涉测试系统(DISAR)对其冲击起爆后的界面粒子速度进行测试。初步的试验结果表明:对于RDX炸药单晶最大生长显露面(210),当冲击压力为18.6 GPa时未能使炸药单晶发生爆轰反应;当冲击压力为36.0 GPa时,根据测试结果计算获得RDX炸药单晶Von Neumann峰值压力为45.4 GPa,查普曼一朱格特(C-J)爆轰对应的界面粒子速度值为2.92 mm/μs,分析认为RDX炸药单晶发生了爆轰反应。更多还原

【Abstract】 In order to study the shock initiation behavior of hexogeon( RDX) single crystals,an octogen( HMX)-based explosive is used to initiate RDX single crystals directly,and the interface velocity profiles of RDX single crystals are measured using a displacement interferometer system for any reflector( DISAR). The shock orientation of RDX single crystal is( 210) plane. The results show that the RDX single crystal is not detonated when the initial shock pressure is below 18. 6 GPa. The RDX single crystal is detonated at the initial shock pressure of 36. 0 GPa since the calculated Von Neumann spike pressure is45. 4 GPa and the interface velocity is 2. 92 mm / μs at the Chapman-Jouget( C-J) point.更多还原
