| 摘 要： | 船舶软搁浅是指船舶搁置在由较软粘土构成的海床或者在柔软的浅滩上的事故。航运业的发展与船舶的大型化趋势使船舶发生软搁浅的风险大大增加，研究船舶的软搁浅性能对船舶设计与制造具有重要意义。本文基于有限元分析软件ABAQUS，选取典型的软搁浅场景，以12,000DWT油船舱段结构为分析对象，研究舱段结构在搁浅过程中的变形、吸能、加速度响应等性能参数。通过系统分析不同速度对船体结构的搁浅性能的影响，全面分析其搁浅性能。本文的相关结论可以为分析船舶软搁浅事故及设计抗冲击舱段结构有一定指导作用。

| Abstract: | Soft grounding means a ship aground on a relatively soft clay seabed or soft beach. The development of the shipping industry and the trend of large ships make the risk of soft grounding greatly increased. Studying the performance of the ship''s soft grounding performance is of great significance to the design and manufacture of the ship. This paper is based on the Finite element analysis software ABAQUS. By selecting a 12,000DWT oil tanker section as the analysis object, study on its deformation, energy absorption, acceleration response and other parameters in typical soft grounding scenarios we choose. Through systematic analysis of the impact of grounding performance under different speeds, study on its grounding performance comprehensively. The conclusion of this paper can provide guidance for analysis of ship grounding and design of section structure. |
