冲击波对含水炸药减敏作用的实验研究

对水胶炸药和乳化炸药在冲击波作用后的爆炸性能作了对比实验研究,结果表明水胶炸药的抗压性能明显优于乳化炸药,分析认为造成这种差别的原因是两种炸药不同的结构组分和敏化方式。用示波器捕捉两种炸药受冲击波作用前后的水中爆炸冲击波,利用冲击波参数计算炸药的减敏程度,将炸药的压力减敏作用数量化,克服了以往的研究方法只能用半爆率、拒爆率等概念计数表述的不足。

Experimental study on the desensitization of water-bearing explosives subjected to shock wave

The explosion properties of a water-gel explosive and an emulsion explosive after subjected to shock compression have been studied. Results indicate that the gel is better than the emulsion, and the preliminary analysis considers that the difference between them in anti-pressing performance is caused by the different structure, ingredients and sensitizing methods. Explosion shock waves produced by the two explosives in water, before and after they compressed by different shocks, are recorded by an oscilloscope, and the parameters of shock waves are used to calculate the desensitizing degree, which quantifies the pressure desensitization and gets over the shortcomings of such quantitative concepts as misfire and half-exploding.
