摘　　要：提出计及摩擦力影响后船舶舷侧加筋板耐撞性能分析的一种简化分析方法,详细讨论了球鼻艏撞击作用下舷侧加筋板的渐进破坏过程,给出了相应的撞击力-撞深曲线和吸收能量-撞深曲线。通过与已有试验结果的比较表明,该简化分析方法能对船舶舷侧加筋板结构的耐撞性能做出合理预报,从而可用于设计阶段评估船体舷侧结构的耐撞性能。A simplified analysis method which takes into account the influence of friction is proposed to evaluate the crashworthiness behavior of stiffened side plates of ship.The progressive collapse behavior of the stiffened side plates collided by a bulbous bow are described.The curves of collision force-penetration depth and energy absorption-penetration depth are presented for the plates and compared with the existing experimental results.The results show that simplified analysis method can well predict the stiffened side plates.The method can be applied to evaluate the crashworthiness behavior of the side structure in ship design.
