| 摘 要： | 采用霍普金森杆装置研究了叠氮化铅(LA)、斯蒂芬酸铅(LTNR)、高氯酸.四氨.双(5-硝基四唑)合钴(Ⅲ)(BNCP)三种起爆药抗高加速度过载的能力,提出了50 MPa压制起爆药柱加速度过载下的受力模型。研究表明,LA、BNCP、LTNR药柱抗加速度过载的临界值分别为5000,5000,10000 g,起爆药药柱先经过短历时的弹性变形后发生脆性断裂,整体具有弹脆性的特征。

| Abstract: | Split Hopkinson Pressure Bar(SHPB) was used to investigate the intrinsic anti-acceleration capability and mechanicalmodel of Lead Azide(LA),Lead Styphnate(LTNR),Tetraammine bis(5-nitrotetrazolato) Cobalt(Ⅲ) Perchlorate(BNCP).Results show that,the intrinsic anti-overload capabilities of LA,BNCP and LTNR are 5000 g,5000 g,10000 g respectively.Primary explosive charge suffered a short elasticity deformation,and then the brittle fracture occured. |

| Keywords: | military chemistry and pyrotechnics primary explosive high acceleration over loading split Hopkinson pressure bar mechanical model |
