摘　　要：为分析新型钝感炸药2,6-二氨基-3,5-二硝基吡啶-1-氧化物(ANPy O)的热响应规律,利用Fluent软件建立了带壳炸药烤燃模型,对ANPy O在不同升温速率下(1℃/min、2℃/min、10℃/min、20℃/min、80℃/min、140℃/min)的烤燃情况进行了数值仿真模拟,并与钝化黑索今(RDX)进行了比较。结果表明:随着升温速率增大,炸药点火时间缩短;在同一个升温速率下,ANPy O的点火时间是钝化RDX的1.6倍左右,点火温度比钝化RDX高出145℃左右,可见ANPy O热刺激钝感于钝化RDX。In order to analyze new passive explosive ANPyO＇ s thermal response regularity, the cook-off model of shelled explosive was es- tablished based on software Fluent and it was used for simulating the explosive ANPyO＇ s cook-off situation at different heating rate （ 1 ℃/ min, 2℃/min, 10℃/min, 20℃/min, 80℃/min, 140℃/min） , and compared with passive RDX. The result shows that：with the heat- ing rate increases, explosive＇ s ignition time decreases. Under the same heating rate, ANPyO＇ s ignition time is 1.6 times of passive RDX, and the ignition temperature of ANPyO is higher than passive RDX about 145 ℃. Therefore, ANPyO＇ s thermal stimulus sensitivity is in- sensitive to passive RDX.
