| 摘 要： | 为改善HTPB基PBX炸药的易损性，研究了炸药的模量与撞击感度之间的关系。通过改变端羟基聚丁二烯（HTPB）基PBX的固化参数与黏结剂的含量，制备了一系列具有不同模量的PBX，利用50％特性落高法对其撞击感度进行测试。结果表明，PBX的撞击感度随抗张模量和压缩模量的下降而降低。从理论上分析了影响撞击感度的模量因素和机理，认为通过调整PBX的力学性能可改善PBX炸药的机械撞击感度。

| Abstract: | In order to improve the vulnerability of HTPB-based plastic-bonded explosives(PBX),the correlations between the impact sensitivity and modulus of the PBX were studied.A series of HTPB-based PBX with different mechanical modulus were prepared by varying curing parameters or content of HTPB.The impact sensitivity of the PBX was characterized by H_(50) drop height.The results show that the impact sensitivity of the PBX was different.The impact sensitivity decreases with the reduction of tensile and compress modulus of the PBX.The mechanism and factors of modulus affecting impact sensitivity were theoretically analyzed,considering that the impact sensitivity could be adjusted by the mechanical properties of the PBX. |
