摘　　要：目的研究低成本高效慢速烤燃试验方法。方法利用自主研发的一套慢速烤燃试验装置,以1℃/min和3.3℃/h升温程序作为对比试验,设置几种三阶段升温程序,对JBO-9013和JH-14炸药进行慢速烤燃试验,以此获得不同升温程序下试样的响应温度和响应等级。结果1℃/min、3.3℃/h、三阶段(100/150/193℃)升温程序下,JBO-9013响应温度分别为243.1、199.5、199.8、201.4、193.0℃,响应等级均为燃烧反应;JH-14响应温度分别为211.0、186.0、191.7℃,响应等级均为爆轰反应。结论升温程序对JBO-9013和JH-14响应温度和响应剧烈程度均有影响。与GJB 8018—2013中1℃/min升温程序相比,三阶段升温程序与MIL-STD-2105D和STANAG 4439中3.3℃/h烤燃试验结果吻合度较高。因此,三阶段升温程序具有缩短试验周期、提高试验效率和降低试验成本的作用。Objective To study the low cost and high efficiency slow cook-off test method.Methods The 1℃/min and 3.3℃/h heating program was taken as comparative tests to set several three-stage heating programs and carry out slow cook-off test on JBO-9013 and JH-14 explosives with a self-developed slow cook-off test device to obtain the response temperature and response grade of the samples under different heating programs.Results The response temperature of JBO-9013 was 243.1,199.5,199.8,201.4,193℃respectively,and the response grades were all combustion reaction at the 1℃/min,3.3℃/h,three-stage(100/150/193℃)heating programs.The response temperature of JH-14 was 211.0,186.0,191.7℃respectively,and the response grades were all detonation reaction at the 1℃/min,3.3℃/h,three-stage(100℃)heating programs.Conclusion The temperature program has an effect on the response temperature and violent degree of JBO-9013 and JH-14.The results of three-grades heating program is obviously closer to the 3.3℃/h heating program of MIL-STD-2105D and STANAG 4439 in terms of slow cook-off test results compared to the 1℃/min heating program of GJB8018-2013.Therefore the three-stage heating program test method can shorten the test time,improve the test efficiency and reduce the test cost.
