摘　　要：根据等效缩比原则,设计了某舰船舱室的1:8等效缩比模型,进行双点装药同步内爆炸试验,对比分析了双点装药同步内爆炸和单点装药内爆炸的爆炸效应特征,研究了这两种爆炸对缩比舱室的毁伤情况。结果表明,双点装药同步爆炸时,冲击波在装药中心面上相互叠加,冲击波冲量效应比同药量单点爆炸显著增加,可有效提高对该类舱室的毁伤能力。Based on the equivalent reducted-scale principle,a 1: 8 equivalent reducted-scale model was designed for a typical ship cabin. The double-point inner explosion test was conducted on the model. The inner explosion effect features with double-point charge and single-point charge were contrastively analyzed. The damage effect of the reducted-scale cabin model was studied. The results showed that when the double-point charge simultaneously explodes,shock waves mutually overlapped on the charge central surface,the momentum effect of shock waves is much larger than that when the single-point charge explodes,so the double-point charge simultaneous inner explosion can effectively increase damages to such a ship's cabins.
