对于大当量爆炸容器设计,准确的爆炸近区正反射冲击波压力和冲量数据至关重要.通过实验方法获得了比距离为0.098～0.5 m/kg~(1/3)范围内球形装药爆炸正反射冲击波压力峰值、冲量和冲击波到时,并结合文献[1-2,4]中的数据,拟合得到了压力峰值、比冲量和比例时间与比距离的经验关系式.结果表明:压力峰值随比距离增大呈指数衰减;反射冲量与爆炸当量成正比,与距离的平方成反比.

The accurate pressure and impulse of reflected blast Wave are very significant for the design of explosive vessel which can contain large explosive. The pressure, impulse and shock travel time of normal reflected blast wave were obtained by means of experiments at the range of the sealed distance is 0.098～0.5 m/kg~(1/3). The experience equations of the pressure, the scaled impulse and the scaled shock travel time vs. the scaled distance were fitted respectirely with the data in this paper and the lit-eratures. The investigated results indicate that the pressure attenuates exponentially with the scaled distance increasing, the reflected impulse is directly proportional to the explosive equivalent and in-versely proportional to the square of the distance.
