为研究高能叠氮硝胺发射药的动态力学强度及影响因素，以现有配方DAGR1为基础，通过调节组分设计制备了4种21／19粒状发射药，低温（－40℃）下对其进行了落锤撞击试验。结果表明，撞击初速为4．0 m／s 时， DAGR1的临界撞击能约为33 J／cm2；在配方中添加质量分数1．5％的热塑性弹性体（ETPE）及混合增塑剂总含量不变增加DIANP含量均可提高样品的低温抗撞击损伤强度。
為研究高能疊氮硝胺髮射藥的動態力學彊度及影響因素，以現有配方DAGR1為基礎，通過調節組分設計製備瞭4種21／19粒狀髮射藥，低溫（－40℃）下對其進行瞭落錘撞擊試驗。結果錶明，撞擊初速為4．0 m／s 時， DAGR1的臨界撞擊能約為33 J／cm2；在配方中添加質量分數1．5％的熱塑性彈性體（ETPE）及混閤增塑劑總含量不變增加DIANP含量均可提高樣品的低溫抗撞擊損傷彊度。

In order to study the dynamic mechanical strength and influence factors of high energy azidonitramine gun propellant,four kinds of 21/19 granular gun propellants were prepared based on formulation of DAGR1.The drop weight tests of samples were conducted at low temperature(-40℃).Results indicate that the critical impact energy of DAGR1 is 33 J/cm2 when the impact velocity is 4.0 m/s.The impact fracture property of sample improved signifi-cantly at low temperature(-40℃)with 1 .5%additive of energetic thermoplastic elastomer (ETPE)and the increase of proportion of 1 ,5-diazido-3-nitrozapentane (DIANP).
