摘　　要：为研究引信传爆管在快速烤燃作用下的热响应规律,对考虑导爆药柱作用的聚奥-9C(JO-9C)装药的引信传爆管进行了快速烤燃实验。利用Fluent对引信传爆管在60 K/min升温速率下快速烤燃过程的热响应规律进行了数值模拟,并与烤燃实验结果进行了对比验证,标定了JO-9C的活化能与指前因子,分别为1.69×10~5J/mol与2.1×10^(15)s^(-1)。基于引信传爆管的快速烤燃实验和模型参数,对15、35、75 K/min三种不同升温速率下引信传爆管的快速烤燃过程进行了数值模拟,结果表明:在引信传爆管点火时,传爆药柱先发生热反应,引起导爆药柱发生爆燃;在不同的升温速率下,点火位置均在传爆药柱边角;随着升温速率的增加,点火时传爆药柱边角处温度增加。To study the thermal response law of fuse booster under fast cook-off action,the fast cook-off test of JO-9C charge of fuse booster is conducted under the action of detonating explosives. The thermal responses of the fast cook-off model are calculated by the finite element program Fluent at the heating rate of 60 K / min. The simulation results are verified by experiments. In addition,the decomposition activation energies and the frequency factor of the reaction of JO-9C are determined to be 1. 69 × 10^5 J / mol and 2. 1 × 10^15s^-1 respectively. Based on the fast cook-off test and the model parameters,the calculations are conducted to simulate the fast cook-off tests at three different heating rates： 15,35 and 75 K / min. The results show that when the fuse booster is ignited,the thermal reaction of booster charge results in the explosion of detonating explosive; the ignition location is all on the corner of the booster charge at different heating rates; the temperature of the corner of the booster charge will rise with the increase of the heating rate.
