摘　　要：为了获得与DNTF基炸药匹配的传爆序列设计技术,通过试验和数值仿真方法开展了该炸药的起爆传爆特性研究,结果表明:试验和仿真得到该炸药的临界直径分别为4.96 mm和5.2 mm,二者基本吻合,误差仅为4.84%。起爆药长径比分别为0.25、0.5、0.75、1、1.25、1.5时,炸药的最小起爆药量分别为0.44、0.48、0.5、0.67、0.84、1 g,最小起爆药量随起爆药长径比的增加而逐渐增加。该研究成果可为该炸药的传爆序列设计提供基础数据。To obtain the detonation sequence design technology matched with DNTF-based explosive,experiment and simulations are carried out to study the detonation characteristics of the explosive.The critical diameters of the explosives obtained from test and simulation are 4.96 mm and 5.2 mm,respectively,which are basically coincident with each other with an error of only 4.84%.When the length-to-diameter ratio of the initiating charge is 0.25,0.5,0.75,1,1.25,1.5,the minimum initiating charge of the explosive is 0.44,0.48,0.5,0.67,0.84,1g,respectively,the minimum primary explosive quantity increases gradually with increase of the length-diameter ratio of the primary explosive.Research results can provide basic data for the detonation sequence design of the explosive.
