本文对高速破片与冲击波载荷联合作用下典型舰船舱壁结构的动态响应过程进行数值模拟研究。基于结构吸能和破片平均剩余速度的评判标准，对比分析3种新型夹芯板双层舱壁（I型、X型、V型）抗冲击毁伤特性。研究结果表明，在相同高速破片与冲击波载荷联合作用下，破片穿透V型夹芯板双层舱壁结构的平均剩余速度最小，并且V型夹芯板结构吸能最多；3种新型夹芯板舱壁结构抗冲击性能均强于典型单层舱壁结构。
The numerical simulation of the dynamic response of typical ship bulkhead structure under combined action of high-speed fragment and shock wave loading was carried out. With the evaluation criteria Based on structural energy absorption and average residual velocity of fragments, we contrast and analysis the shock damage characteristics of the sandwich double bulkheads structure (I、X、V-type). The results show that:under the same combined load, we can get a smallest average residual velocity of fragment while the fragments penetrate the V-type sandwich double bulkheads structure. At the same time, the V-type sandwich double bulkheads structure absorbs the most energy. These three kinds of sandwich plate structures all have better anti-Impact damage property than the typical bulkhead structure.
