摘要
通过对爆炸冲击波在空气中传播的已有研究成果进行了对比分析,提出了一个能较好描述冲击波超压峰值与当量比例距离关系的解析式。通过静止装药爆炸试验,测得距爆心不同距离处的超压-时间曲线,实测值与理论值能较好吻合,但是在距离爆心较近处仍存在一定偏差,并且实测曲线受到反射波影响较大。
Through the comparative analysis of the existing research results of blast shock wave propagation in air, the analytical formula of the relationship between the peak value of overpressure and the proportional distance was summarized. Through the static loading explosive test, we measured overpressure time curves from the explosion of heart at different distances. The measured values are in good agreement with the theoretical data, but from explosive center nearer, there still exist certain deviation, and the measured curve by reflection wave effect is large, so it is necessary to further research on the explosion shock wave.
