摘要
为研究药柱爆炸冲击波在酚醛层压材料中的衰减特性,利用锰铜压阻传感器,测量了药柱爆轰输出冲击波经不同厚度酚醛层压材料隔板衰减后的冲击波压力,并计算得到冲击波波后质点参数。结果表明:药柱爆轰输出冲击波经酚醛层压材料隔板传播时,其峰值压力随隔板厚度增加呈指数型衰减,通过对实验数据的拟合,得到酚醛层压材料中的冲击波衰减规律。
In order to study the characteristics of shock wave attenuation in phenolic cotton fabric material, the explosive detonation wave from charge was transmitted through phenolic cotton fabric material with different thickness, and the attenuated shock wave pressure was measured by manganin gauge, as well as the impact of particle parameters after wave was calculated. The results show that the shock wave is obviously attenuated in the transmission process of the phenolic cotton fabric material, and the attenuation law of shock wave is obtained by fitting the experimental data.
