摘要
给出一种计算船体结构基本构件——梁、板耐撞性的简化分析方法,并将该方法应用于单壳船舷侧结构的碰撞分析。讨论了球鼻首撞击作用下单壳船舷侧结构的总体破坏模式及其渐进破坏过程,提出了计及渐进破坏过程的碰撞损伤简化计算方法。实例计算结果表明:该简化分析方法能对单壳船舷侧结构的耐撞性作出合理的预报,可应用于船舶设计阶段船体结构耐撞性能的评估。
A simplified analysis method is proposed to evaluate the damage of beam and plate in ship collision. The method is used to analyze the crashworthiness of side structure of the single-hull. The overall failure mode and its progressive destruction process of the single-hull structure collided by the bulbous bow are investigated in detail. The simplified analysis approach which takes into account the gradual destruction process is presented. Example indicates that the simplified analysis method can predict the structure damage of the single-hull reasonably. It can be used to evaluate the crashworthiness of the structure in ship designing.
