摘要
为研究固体温压炸药主体组分及配比对爆炸性能的影响规律,在1 kg量级装置静爆试验的基础上采用灰色关联方法分析5种组分原材料对冲击波超压的关联程度。结果表明,与距爆心3 m处冲击波超压正相关的因素依次为:高能炸药(RDX)、超细AP(3μm);而与距爆心9 m处冲击波超压则为:特细铝粉Ⅱ(6μm)、特细铝粉Ⅰ(25μm)、工业AP(120μm)。说明,高能炸药、超细AP对较近距离冲击波超压具有主要贡献,而对较远距离冲击波超压贡献作用较小;两种粒度的特细铝粉和工业AP对不同距离处冲击波强度的作用则与之相反。
Based on the blast field test results of 1 kg thermobaric explosive,the method of grey correlation analysis was used to investigate the influence rule of 5 raw materials and their contents on blast performances.The results show that the reduced order of the positive correlative factors investigated to the overpressure at 3 m from the explosion center is： high explosive RDX,fine particles of ammonium perchlorate（AP）;and with the overpressure at 9 m is： fine particles of aluminum powder Al（Ⅱ）,coarse particles of aluminum powder Al（Ⅰ） and coarse particles of amonium perchlorate（AP）.It indicates that high explosive RDX and fine particles of AP are in favor of the overpressure at 3 m,but weaken the overpressure at 9 m.Whereas the aluminum powder with two particles size and the coarse particles of AP have the inverse influence on overpressure at both distances.
