Influence of explosive mass and heating rate on cook-off response characteristics of DNAN based casting explosive

  • 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。
