云雾爆炸场超压的威力研究

POWER INVESTIGATION OF OVERPRESURE ON THE FAE BLAST FIELD

为了研究FAE爆炸场超压规律 ,对FAE和TNT进行了静爆对比试验 ,获得了各自的爆炸场超压实测数据 .分析得到了各自的拟合公式、曲线及TNT当量值 .研究结果表明 ,FAE爆炸场超压规律与TNT有显著区别 ,可划分为云雾爆轰区和冲击波作用区 ,其中云雾爆轰区是强毁伤区 .在云雾区 (爆炸近场 ) ,FAE超压值很低但近似相等 ,TNT具有高超压但衰减迅速的变化规律 .在冲击波作用区 (爆炸远场 ) ,FAE和TNT超压分布具有某种“相似性” ,均呈衰减趋势 ,其中尤以TNT衰减更为迅速 .

In order to study the laws of overpressure on the FAE blast field, FAE and TNT were investigated in the static blast way. Experimental results of overpressure were obtained, Attaining separate fitting formulas, curves and TNT equivalent. Investigational results indicated that the laws of FAE overpressure have great difference with TNT. It is divided into two zones. They are cloud zone and shock wave zone. In which, cloud zone is strong damage zone. In the shock wave zone, overpressure is very low but almost the same. TNT maintained high overpressure but decayed very quickly in the zone. In the shock wave zone, the laws of overpressure on the FAE and TNT had the same comparability which is rapidly decayed. Especially the overpressure of FAE decayed more slowly than that of TNT in the zone.
