摘要

To investigate the thermal reaction law of PBXC10 explosive, the multi-point temperature measuring cook-off tests were carried out at different heating rates. The explosive temperatures were measured from its edge to its center. An explosive cook-off test model was set up. The numerical simulations were conducted to calculate the explosive thermal reaction. According to measured T-t curves of explosives, the activation energy and frequency factor of PBXC10 explosive were obtained. The thermal reaction characteristics of explosive at various heating rates were analyzed. Based on the direction of heat transfer, the cook-off tests were described in three forms of slow cook-off test, medium cook-off test and fast cook-off test. The thermal explosion processes of PBXC10, JB9014 and JOB9003 explosives were calculated at different temperatures. The results show that the heat sensitivity of PBXC10 explosive is between those of JB9014 and JOB9003.
