摘要


摘要:未来海军舰船将承担起越来越多的近海作战任务,对舰船在近海作战的生命力研究也就显得越发重要。钢夹层板是一种新兴的夹层式结构,为了解该结构的抗爆性能,计算和分析了近场水下爆炸载荷作用下普通钢板和钢夹层板的动态响应,两种板的单位面积质量相同,计算结果与实验结果符合较好。研究结果表明,钢夹层板在抗变形能力和吸能能力方面较普通钢板具有很大优势,尤其是其保持结构完整性的能力远强于普通钢板。将钢夹层板引入中小型水面舰船的舷侧防护改进和设计,能够提高结构的刚度,减少结构焊接工作量及焊接变形,是提高舰船生命力的一种有效手段。

Abstract

Abstract: Naval ship will take on more and more offshore mission in future. As a result, research on ship vulnerability in the offing becomes more important. Steel sandwich plate is a new type of sandwich structure. To understand its blast-resistance, the dynamic responses of both steel plate and steel sandwich plate with the same mass suffer proximity underwater explosion loading are simulated with finite element method. The calculation results accord with experimental phenomenon. Results of the study indicate that the deflection-resistance and energy absorption capability of steel sandwich plate are better than that of original steel plate, especially its competence on keeping integrity of structure. Steel sandwich plate can be introduced into the innovation and design of medium and small sized ship to improve stiffness of structure, ship vulnerability and reduce welding.
