摘要

摘要: 为了研究不同药量和升温速率条件下DNAN基熔铸炸药的慢速烤燃特性，自行设计了烤燃实验装置，采用多点测温烤燃实验方法，分别在1和0.055℃/min两种升温速率下进行了不同状态装药量的烤燃实验，分析了熔铸混合炸药的热反应特征。结果表明，装药量和升温速率共同影响烤燃弹的响应特性。相同烤燃弹在0.055℃/min升温速率下比在1℃/min升温速率下加热响应会更剧烈；烤燃弹的放置姿态及端盖厚度会影响烤燃弹的响应剧烈程度。

Abstract: We studied the effect of the explosive mass and the heating rate on the slow cook-off characteristics of DNAN based casting explosive by designing a new roasting test device, and examined the thermal reaction characteristics of the mixed explosive by performing a multipoint temperature experiment at two heating rates, 1℃/min and 0.055℃/min, respectively. The results showed that the explosive mass and the heating rate jointly affected the response characteristics of the roasting bombs. The same roasting bombs at the heating rate of 0.055℃/min was more intense than that at the heating rate of 1℃/min. The placement posture and the thickness of the end cover also affected the intensity of the response of the roasting bombs.
