【摘要】 本文采用高速摄影方法测试温压炸药爆炸火球和爆炸冲击波的传播过程,通过与压力传感器同步测试结果的相互验证,确定了爆炸冲击波与爆炸火球的分离位置。由高速摄影的测试结果可直观地说明温压炸药的爆炸冲击波形成机理和火球的后效发展过程。
【Abstract】 The paper presents a way to take measurement on the fireball and Shockwave spreading traces using high speed camera on thermobaric explosion field. According to the results validated one another by camera and piezoelectricity sensors’ measures in phase, the position which Shockwave separates fireball was determined. The high speed camera’s photographs illuminate directly the Shockwave’s forming mechanism and the fireball spreading process and aftereffects on thermobaric explosion field..
