水介质对舱内爆炸抑制作用的实验研究

摘要

In this work,we investigated a study of the mechanism governing the internal blast in a warship cabin and the technique for preventing it.We developed a multi-cabin structure and carried out experiments with/without water were on the cabin to record and compare such data as the blast process,the peak pressure,the specific impulse and the quasi-static pressure.The results showed that (1) water could obviously reduce the peak pressure,the specific impulse and the quasi-static pressure,that (2) within a certain range,the greater amount of TNT,the more obvious the attenuation,and that (3) water could constrain the afterburning phenomena and TNT reaction,thereby affecting the formation of the quasi-static pressure.%为探索舰船抗舱内爆炸的机理和技术手段,设计了多舱室缩比模型,开展了有水和无水介质的爆炸实验,对比了爆炸当舱水介质对爆炸反应过程、邻舱冲击波峰值、比冲量及准静态压力的影响.研究结果表明:(1)水介质对舱内爆炸邻舱冲击波峰值、比冲量和准静态压力均有明显的衰减作用;(2)在一定区间内,炸药当量越大,水介质抑制内爆炸的效果越明显;(3)水介质能有效阻碍燃烧等爆炸后续效应,影响准静态压力形成.
