摘要
为研究温压炸药在全密闭空间内冲击波特征,在双层密闭的爆炸容器中测定了等质量与等体积条件下,不同含铝量的温压炸药的超压及冲量,并采用AUTODYN软件对容器中的冲击波传播进行了模拟分析。等质量与等体积两种装药方式下的研究结果均表明,数值模拟能很好地对试验数据进行拟合,在密闭空间内温压炸药铝粉质量分数为30%时,冲击波的超压与冲量最大。
In order to research the shockwave parameters of thermobaric explosive in fully enclosed space,the overpressure and impulse of thermobaric explosives with different Al content were measured under the same charge volume and charge mass respectively in a double-layer enclosedblast chamber. Furthermore,the numerical simulation of shock wave propagation has been carried out by using the AUTODYN software. Results show that propagation process of shock wave by numerical simulation agreed well with experiments,and the charge with 30% aluminum content（ mass fraction） achieves the best performance under both equal volume and equal mass.
