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。
To verify impact safety and implosion power of a composed charge, the drop hammer tests and implosion power experiments were conducted. The results show that critical height of the single thermo-baric explosive is 2.2 m under loading of 400 kg hammer, while the composed charge did not ignite under height from 2.2 m to 2.7 m, which means that the composed charge holds a better impact safety property. Peak overpressure of the composed charge was 61.9% of the single thermo-baric explosive, the impulse of the composed charge was 99.4% of the single thermo-baric explosive, and the peak quasi-static pressure of the composed charge was 94.5% of the single thermo-baric explosive. Considering energy release characteristics within a limited space, it is more suitable to use peak quasi-static pressure as an evaluation standard. The test results show that implosing energy release characteristics of the composed charge is almost the same as the single thermo-baric explosive.
