40万吨矿砂船货舱段局部强度分析

Cargo Hold Structural Strength Analysis for 400 000 DWT VLOC

介绍了基于DNV规范对一艘40万吨矿砂船的结构强度进行有限元分析。应用DNV的Sesam和NauticusHull软件对该船屈服、屈曲强度进行分析评估，并依据结果对船体结构型式和尺寸进行了优化和加强。其分析结果与加强方案对超大型矿砂船结构的强度分析具有一定的参考价值。

This paper introduced the FEM analysis of a 400 000 DWT VLOC＇ s structure based on DNV Rules. The assessment of yielding and buckling strength was carried out with DNV software Sesam and Nauticus Hull. According to the results, we optimized and strengthened the structures. The results and strengthening method could serve as reference for the assessment of very large ore carrier＇ s structure.
