夹层板系统(SPS)具有优良的力学性能,因此被广泛地应用于船舶修造过程。因其夹芯层具有良好的缓冲作用,所以可以用作耐撞结构以提高舰船的碰撞性能。文章基于大型商业有限元分析软件ABAQUS,分析了SPS舷侧结构的碰撞性能,重点讨论了损伤变形、碰撞力和能量吸收等碰撞参数,并与传统舷侧结构的碰撞性能进行比较。研究表明:SPS舷侧结构较传统舷侧结构在总质量相当的情况下,极限撞深提高且在极限撞深时吸能也提高较多,表现出了优越的耐撞性能。
Sandwich Plate System(SPS) with superior mechanical performance is widely used in ship repairing. The core has good buffer function so that it can be used as crashworthiness structures.Based on ABAQUS, the crashworthiness of SPS side structure under collision load was analyzed, such as damage deformation, collision force and energy absorption. Then the crashworthiness of SPS was compared with traditional side structure. The results show that SPS side structure has better crashworthiness than traditional side structure.
