基于ABAQUS的船舶搁浅数值仿真研究

Numerical Simulations of Ship Grounding Using ABAQUS

  • 摘要: 船舶搁浅性能研究是船底结构设计的一个重要环节。应用国际上通用的动力有限元程序ABAQUS/EXPLICIT对船舶搁浅动力学过程进行仿真研究。通过系列仿真试验,对不同搁浅位置及摩擦系数的情形下船底结构的搁浅性能,包括结构的损伤变形、搁浅力和能量的吸收分别进行对比和分析,得到一部分重要的结论,为船舶搁浅性能的评估及结构优化设计提供重要依据。

     

    Abstract: Ship grounding should be considered as a critical factor in the design of ship bottom. A general commercial FEA package ABAQUS/Explicit is used to model and analyze the dynamic behavior during ship grounding. Ship bo ttom grounding performances, such as deformation due to damage, grounding forces and energy absorption, are obtained and compared under the combination of varied grounding positions and friction coefficients. Some conc lusions are drawn and can be advices to ship grounding evaluation and design optimization.
