炸药殉爆的连续压导速度探针判定方法
|
摘要
为了更可靠、更直观地判定炸药的殉爆情况,基于自行研制的连续压导速度探针,设计了一种可以量化判定炸药殉爆的测试方法;利用该法对不同RDX/铵油炸药(ANFO)比例的混合装药进行了测量,给出了测试曲线可能出现的3种结果作为判定炸药殉爆的依据,对RDX/ANFO(质量比50%/50%)的混合装药进行了多组重复性实验,得到其殉爆距离,并对主发装药和被发装药的爆速进行拟合。结果表明,当爆轰波-冲击波总行程等于主发装药、被发装药和空气间隔的总长度时,说明被发装药发生殉爆,当行程小于总长度时,则表示未殉爆;RDX质量分数为0和15%时殉爆距离小于20mm,RDX质量分数为50%时殉爆距离为220mm;连续压导探针所能记录的空气冲击波的最大间隔为60mm,而殉爆的被发装药爆速与主发装药基本一致,两者相差0.02%～4.4%。表明连续压导探针法可以可靠并定量地判定炸药的殉爆情况。
To assess the sympathetic detonation of explosives more reliably and more intuitively, a testing method for quantitative determination of sympathetic detonation of explosives was designed based on a self-developed continuous velocity probe. Using this method, measurements for mixed charge with different mass ratio of RDX/ANFO were performed and three possible results of test curves were given as the basis for determining the sympathetic detonation. A series of repeated experiments were carried out for the mixed charge of RDX/ANFO(mass ratio of 50%/50%), whose sympathetic detonation distance was determined and the detonation velocities of donor charge and acceptor charge were fitted. The results show that when the total distance of detonation-shock wave is equal to the total length of the donor charge, acceptor charges and the air gap, it means that the acceptor charge is initiated, while the total distance is less than the total length, it means that the acceptor charge is not initiated. The transmission distances are less than 20 mm when the mass fraction of RDX is 0 and 15%, while equals to 220 mm if the mass fraction of RDX is 50%. The maximal gap distance of air shock wave recorded by continuous pressure-conducted probe is 60 mm. The detonation velocities of initiated acceptor charge are basically equal to the values of donor charge, whose difference between them is between 0.02% and 4.4%. Indicating that the continuous pressure-conducted probe method can assess the sympathetic detonation of explosives reliably and quantitativly.
