【摘要】：基于有限元分析軟件ABAQUS,選取典型的軟擱淺場景,以12 000 DWT油船艙段結(jié)構(gòu)為分析對象,研究其艙段結(jié)構(gòu)在擱淺過程中的損傷變形、吸能、擱淺載荷等性能參數(shù)。此外,通過改變船舶初始擱淺速度討論擱淺速度對船體結(jié)構(gòu)擱淺性能的影響規(guī)律,豐富擱淺場景,全面評估其擱淺性能。研究結(jié)論可以為相關(guān)船舶設(shè)計規(guī)范的制定及擱淺事故救援等提供參考。
[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.
