金属夹层结构的舰船应用研究综述

Application and Prospect of Steel Sandwich Panels in Warships

金属夹层结构作为一种未来工程应用的新型结构,在舰船领域有着广阔的应用前景。立足于水面舰船背景,从金属夹层结构的基本类型、在舰船中的应用、抗爆抗冲击性能分析以及目前存在的技术难点等几个方面进行综述,发现在此领域有4个方面的问题亟待解决:应系统地开展舰用金属夹层结构的相关基础研究;需尽快系统地开展关于波纹夹芯板的相关研究;在相关基础研究的基础上,开展设计技术研究;开展大量试验研究工作,降低设计风险。

As an innovative type of structure in future engineering applications, the steel sandwich panel already shows wide application prospect in shipbuilding and is in dire need of domestic systematical re- searches. By focusing on surface ship applications, the steel sandwich panel is reviewed in this paper in four aspects： basic types, the application in ships, mechanical property analysis, and current technical challenges. Through this analysis, four relevant problems have emerged ： firstly, the systematic research of marine steel sandwich panels is urgently needed; secondly, the lightweight corrugated core sandwich pan- el, welded with laser beam, requires immediate and profound studies ; thirdly, the design technique of steel sandwich panels on warships should be investigated based on pre-mentioned fundamental research- es ; fourthly, a great number of experiments should be conducted to lower the design risk.
