摘要:
为进一步研究导爆管的传爆过程,用高速摄像机对导爆管的传爆过程进行研究。对图像进行处理分析,得到导爆管爆轰的成长规律,用智能五段爆速仪对测得的稳定爆速进行验证;对出口冲击波进行分析,得到出口冲击波的传播规律,同时又验证了达到稳定爆速的最短距离。结果表明:爆轰有效反应区长度为13 cm,稳定传爆时导爆管最短约为40 cm,传爆速度为1 750 m/s;爆轰成长过程为先缓慢增长,后高速增长,再缓慢增长至稳定。出口冲击波传播速度是波动的,波速上升是因为发生了口外爆炸。
Abstract:
High-speed camera was used to understand the detonating process of the nonel tube. The image was processed and analyzed to obtain the detonation growth rule of detonation tube, and the measured stable detonation speed was verified by intelligent five-stage detonation velocity meter. The export shock wave was analyzed to obtain the propagation rule of export shock wave, and the shortest distance to achieve the stable detonation speed is verified. Results show that the effective reaction zone length of detonation is 13 cm, the minimum detonation tube length is about 40 cm, and the detonation speed is 1 750 m/s when the detonation is stable. The process is first slow growth, then high-speed growth, and then slow growth to stability. The propagation velocity of the exit shock wave fluctuates, and the explosion occurs outside the mouth during the rise of the wave velocity.
