Internal load characteristics of broadside cabin of defensive structure subjected to underwater contact explosion

  • 摘要: 采用模型实验方法,研究了近自由面水下接触爆炸下防雷舱舷侧空舱的内压载荷特性。根据实验模型的破坏结果和压力测试结果,分析了水下爆炸产物与防雷舱舷侧空舱的相互作用过程以及水下爆炸产物的压力变化规律。研究表明:防雷舱舷侧空舱的载荷可分为冲击波载荷、准静态压力载荷和负压载荷3种,防雷舱舷侧空舱的破坏主要由冲击波载荷和准静态压力载荷造成,并且准静态压力载荷的比冲量是冲击波载荷的数倍,而负压载荷对防雷舱舷侧空舱破坏的影响可忽略不计。
