摘    要:为研究PBX炸药在冲击作用下的物理损伤、化学损伤及成热的物理机制,采用炸药爆炸驱动隔板实验技术对PBX炸药进行了冲击压缩实验,回收炸药试样并对其不同位置处的断面形貌进行SEM分析.结果表明,随着冲击能量的增加,其温度效应的影响越来越显著,损伤模式从物理损伤向化学损伤过渡.这为XDT问题中的"热点"形成机制等研究提供了实验基础.

Abstract:In order to study the physical mechanisms of the physical and chemical damages of PBX, and the mechanisms of heat formation, the shock compression experiments on PBX have been done using explosive driving gap experiment. The meso-structure of damaged samples in the different position was observed using SEM. The result shows that the effect of temperature significantly increases with the increase of impact energy, and the damage mode transits from the physical damage to the chemical damage. This provides experimental basis for studying the formation mechanism of hot-spot in XDT.
Keywords:explosion mechanics  PBX  damage mode  shock compression  initiation mechanism
