摘要
设计了改进的隔板实验装置,采用PVDF压力计测量受试炸药的入射压力,利用高速分幅相机得到炸药自由表面发展变化过程。通过分析计算得到入射压力与自由表面粒子速度之间的关系,并与未反应炸药计算的自由面粒子速度进行了比较,得到JO-9159炸药在低冲击作用下的化学反应阈值和点火阈值分别为1.13和1.98GPa。
The modified gap test setup was designed.The input pressure of acceptor explosive was measured by applying a PVDF gauge,and the motion images of the free surface were recorded by using a high-speed frame camera.The relation between the free-surface particle velocity and input pressure of explosive were obtained and compared with the calculated free-surface particle velocity of unreacted explosive.Comparison shows that the chemical reaction threshold and ignition threshold of explosive JO-9159 are 1.33 and 1.98 GPa,respectively.
