碰撞载荷下船舶结构的变形与失效一直是业界的研究热点,但以往的研究并没有深入分析舷侧结构的失效形式。本文通过对各种不同撞击参数舷侧结构碰撞模式的数值模拟,分析了舷侧结构的失效模式。结果表明,船舶碰撞载荷下舷侧结构失效主要体现在局部塑性变形,甲板手风琴式撕裂,外板撕裂,以及横框架的屈曲。
The deformation and failure of the ship structure under collision load is the focus of the ship mechanics. However, the research work in the past always ignored the failure mode of the side structure. In this paper, the failure mode of side structure is analyzed by numerical simulation of different impact parameters in the collision.The results show that the failure of side structure is mainly reflected in local plastic deformation, deck accordion tearing, outer plate tearing, and transverse frame buckling.
