Experimental Study on Impact Safety and Implosing Energy Release Characteristics of Composed Charge

  • 摘要: 为了验证某组合装药的撞击安全性与内爆威力,开展了组合装药的大型落锤试验及爆炸罐内爆威力试验研究。结果表明:单一温压炸药在400 kg落锤作用下的临界落高为2.2 m,组合装药分别在2.2、2.3、2.5和2.7 m落高时均未发生爆炸反应,证明组合装药具有更好的撞击安全性;组合装药的初始冲击波超压峰值是单一温压炸药的61.9%,比冲量是单一温压炸药的99.4%,准静态压力峰值是单一温压炸药的94.5%。考虑到炸药在有限空间内爆炸的能量释放特性,将准静态压力峰值作为威力评价标准更为合适。试验结果证明组合装药的内爆威力与单一温压炸药相当。
