炸药安全性的火箭橇实验研究

 采用双轨火箭橇加载装置，对PBX-1炸药结构件进行了“靶打弹”撞击实验，采用PVDF计和压电石英计，测量炸药中入射压力和反应压力的变化情况；通过高速摄影和大画幅照相，观察了炸药件受撞击后发生反应的直观图像和靶、弹撞击的细节过程；利用冲击波超压传感器，测量了炸药反应后的超压曲线，并估算了其相对能量释放率。初步实验结果表明，当入射压力为0.48 GPa时，炸药发生部分爆炸，相对能量释放率约为51.8%。

Experimental Study on Safety of Explosive with Rocket Sled

Explosive configuration of PBX-1 was impacted by dual rail sled loading target, PVDF and quartz gauges were used to test the incident and reacted pressure in explosive. Intuitionistic image and detail of impact between target and configuration were recorded by digital and frame cameras. The curves of overpressure produced by explosive reaction are tested by blast overpressure gauges, and relative release rate of energy is estimated. The results indicate primarily that explosive occurs partial blast and the relative release rate of energy is about 51.8% when the incident pressure is 0.48 GPa.
