摘要:
利用大型落锤和一级轻气炮加载装置对RDX基PBX炸药进行撞击加载实验,获取了不同应力率(0.314~9.83GPa/ms)下的力学响应特性及反应情况,探讨了应力率对该RDX基PBX炸药撞击安全性机理的影响。结果表明,随着应力率的增加,RDX基PBX炸药的撞击安全性降低;PBX炸药颗粒的变形速率随着应力率的增加而增大,热量无法被蜡状添加物在短时间内吸收,使得RDX颗粒温度迅速上升,这是RDX基PBX炸药撞击安全性下降的主要原因。
Abstract:
The impact loading tests of a RDX-based PBX explosive were carried out using large drop hammer and one stage light gas gun loading device. The mechanical response and reaction degree at different stress rates (ranged from 0.314 to 9.83GPa/ms) were obtained. The effect of stress rate on impact safety mechanism of the RDX-based PBX explosive was discussed. The results show that the impact safety of the RDX-based PBX explosive decreases, the deformation rate of explosive particles increase with increasing the stress rates, and the heat cannot be absorbed by the waxy additive in a short period of time and makes the temperature of explosive particles rise rapidly, which is the main reason for impact safety decrease of the RDX-based PBX explosive
