【摘要】：基于有限元分析软件ABAQUS,选取典型的软搁浅场景,以12 000 DWT油船舱段结构为分析对象,研究其舱段结构在搁浅过程中的损伤变形、吸能、搁浅载荷等性能参数。此外,通过改变船舶初始搁浅速度讨论搁浅速度对船体结构搁浅性能的影响规律,丰富搁浅场景,全面评估其搁浅性能。研究结论可以为相关船舶设计规范的制定及搁浅事故救援等提供参考。
[Abstract]:Based on the finite element analysis software Abaqus, the typical soft grounding scene is selected, and the damage deformation, energy absorption and stranded load of the cabin structure during the stranded process are studied with 12 000 DWT oil cabin structure as the analysis object. In addition, by changing the initial grounding speed of the ship, the influence of the grounding velocity on the grounding performance of the ship structure is discussed, and the grounding scenarios are enriched, and the grounding performance is comprehensively evaluated. The conclusions can be used as reference for the formulation of ship design code and the rescue of grounding accident.
