摘要 参照Slape等人的ODTX方法,建立了恒温空气浴的ODTX试验装置和方法,用该法对以TATB、HMX/TATB为基的塑料粘结炸药,在200~300℃进行了一维热起爆延滞期测定,讨论了铝壳密封炸药柱的热起爆延滞期与温度的关系,提出了用较小尺寸炸药柱的ODTX试验结果去推测相同限制性条件下的大尺寸炸药柱的临界温度的方法。结果表明:大尺寸炸药柱的临界温度的计算值与文献值之间的差值在±15℃范围内。 A test setup for measuring the time-to-explosion of thermally initiated explosive cylinders confined in Al-cases was constructed.The plastic bonded explosives based on TATB and HMX/TATB at 200~300℃ were tested by using the setup there-of.A test method for measuring the one-dimension time-to-explosion(ODTX)by thermal initiation is presented.The relationship between the time-to-explosion and the medium temperature is discussed.A method for calculating the critical temperature of large-sized explosive cylinder by using the ODTX results of small-sized explosive cylinders is proposed as well.The calculated results show that the absolute error between the critical temperature values obtained from this method and the experimental data reported is within 15℃
