摘要

SPS(sandwich plate system)夹层结构具有良好的缓冲吸能特性，在舰船抗冲击防护方面具有广阔应用前景。利用落锤碰撞冲击试验设备开展SPS夹层结构动态冲击试验研究，并与加筋板进行抗冲击性能对比分析，探讨SPS夹层结构在落锤冲击载荷下的损伤模式，撞击力变化及能量吸收等特性，获得SPS夹层结构在碰撞载荷作用下的耐撞性性能。试验研究结果表明，在等质量前提下，SPS夹层结构耐撞性能显著优于加筋板，主要通过结构的整体塑性变形和芯层压缩变形吸收冲击能量，使得SPS夹层结构的损伤破口明显小于加筋板，SPS夹层结构的撞击力峰值比加筋板减小28.5%；基于试验数据验证有限元仿真结果的可靠性，对比加筋板计算结果可知，SPS夹层结构吸能增幅为24.33%。研究成果有望为舰船轻量化设计及安全防护设计提供参考。

Abstract

An sandwich plate system（SPS) structure has excellent energy absorption and buffer characteristics, thus it has a broad application prospect in ship impact protection.Dynamic impact experiments of an SPS structure and a stiffened plate were carried using drop hammer impact test equipment.The impact resistance of the SPS structure was compared with that of the stiffened plate.The damage mode, impact force change and energy absorption of the SPS structure under the impact load were discussed.The results show that under the condition of equal weight, the impact resistance of the SPS structure is significantly better than that of the stiffened plate.The impact energy is absorbed mainly through the overall plastic deformation and core compression deformation of the core layer, so that the damage crack of the SPS sandwich structure is obviously smaller than that of the stiffened plate.The peak impact force of the SPS structure is 28.5% less than that of the stiffened plate.The reliability of the finite element simulation results was verified based on experimental data, compared with the calculation results of the stiffened plates, the energy absorption of the SPS structure increases by 24.33%.The research results are expected to provide reference for lightweight design and safety protection design of warships.
