摘要: 液舱是舰船多层防护结构体系中的重要功能舱室,战斗部近距离爆炸时,高速破片和冲击波载荷将对防护液舱产生严重的毁伤效应。针对高速破片和冲击波作用下防护液舱的动态响应特性和毁伤模式,提出了复合防护液舱的结构形式。为了对比该液舱相对常规液舱的抗爆效能,开展了战斗部模型近距离爆炸载荷作用下复合液舱和常规结构形式液舱毁伤的模型试验,得到了战斗部模型破片速度、液舱结构的变形、应变、破口尺寸、舱壁压力等参量。通过对比发现,相对于传统液舱结构,复合防护液舱前面板、后面板最大变形分别减少22.78%和8.47%,结构应变降低30%,冲击波峰值减弱18.62%,该新型结构形式明显提高了液舱抗爆防御效果。

Abstract: The liquid cabin with multi-layer protective structure plays an important role in defending the loadings of combined high-speed fragments and blast wave, which are usually due to the close-in explosion of a cast charge, and cause severe damage to the structure of liquid cabin. A new composite structure of liquid cabin is designed based on the dynamic response characteristics and failure mode of liquid cabin under the synergistic effect of high-speed fragments and blast wave. In order to investigate the anti-blast performance of composite liquid cabin, the traditional liquid cabin and newly designed composite liquid cabin are experimentally test under the blast load of cased charge. The fragment velocity, bulkhead deformation, perforation size, strain and shock wave pressure are obtained. The experimental data are analyzed and compared.It is found that, in the composite liquid cabin, the maximum deformations of front and rear bulkheads are decreased by 22.78% and 8.47%, respectively, the plastic strain is decreased by 30%, and the shock wave peak is decreased by 18.62%.
