摘要
在装填有抛撒药和氟化物的装置中,当中心抛撒药起爆,将氟化物抛出装置时,氟化物会与密闭容器内液体发生剧烈反应,释放大量能量。为了评价该装置在密闭贮液容器内的爆炸威力,基于超压-冲量准则,在模拟密闭贮液容器内进行了爆炸毁伤威力评价实验,并计算得到该装置的TNT当量值。结果表明:该方法简单有效,可作为该装置在密闭贮液容器内爆炸毁伤威力评价的方法和依据。
Based on the fact that in an experimental device filled with explosive and fluoride,the explosion of the central explosive could disperse the fluoride out of the device,then the fluoride would intensely react with the liquid in the confined container and release plentiful energy,three experiments with different explosion depths were carried out in small-scale confined containers to evaluate the damage power of this device according to the overpressure-impulse criterion.And the TNT equivalent mass of this device was calculated.The experiment with the explosion depth of 1.2 m was numerically simulated by using the experimental data.The maximum dispersal velocity of the top cover obtained by simulation is close to the experimental result.It displays that the given evaluation method is feasible.
