利用光纤探针/光电转换器/示波器技术和楔形炸药块方法,采取电炮驱动薄飞片冲击加载产生高压短脉冲激励的装置,测量了一种以TATB/HMX为基炸药的到爆轰距离,研究了到爆轰距离随初始冲击波压力幅值和脉宽的变化关系,给出了这种以TATB/HMX为基炸药的Pop关系曲线和表达式.实验研究结果有助于了解压力脉宽对钝感炸药的冲击起爆和爆轰成长的影响.对于短脉冲冲击加载,入射压力脉宽对炸药得到爆轰距离影响明显,相同实验条件下,压力脉宽越长,炸药的到爆轰距离越短,相同压力脉宽下,加载压力越高,炸药的到爆轰距离越短.

By means of optical fibre probe, optical-electrical converter, and oscillograph diagnostic technique, the run distance to detonation was measured as a function of initial shock pressure in a TATB/HMX-based explosive. High amplitude and short duration shock stimuli generated by an electric gun were used to initiate the cylindrical wedges of explosive material. The experimental technique was described, and the results in the form of POP plots for the TATB/HMX-based formulation were presented. These experimental data may give some insight into the effect of pulse duration on the initiation and growth to detonation characteristics in insensitive high explosives. For the short-duration shock loading, the effect of the pulse duration on the run distance to detonation of explosive is obvious. Under the same experimental conditions, the longer the pulse duration , the shorter the run distance to detonation. And for the same pulse duration, the higher the loading pressure, the shorter the run distance to detonation.
