药量和升温速率对DNAN基熔铸炸药烤燃特性的影响
|
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。
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.
