大型汽车滚装船横向挠曲强度全船有限元分析

Transversal Racking Strength of Large-sized PCTC with Global FEM Analysis

大型汽车滚装船(PCTC)自身结构的特殊性和横向挠曲强度的关键性,对其进行横向挠曲强度全船有限元分析十分必要。以8 000车大型汽车滚装船为研究对象,采用通用软件MSC/PATRAN建立有限元模型,按照ClassNK规范进行载荷的选取和施加,最终得到了横向挠曲强度全船有限元分析结果。对大型汽车滚装船挠曲强度的直接计算有一定的指导作用。

Due to the crucial transversal racking strength and the special structure characteristic, it is necessary to calculate the transverse racking strength with global FEM analysis for large-scale PCTC. Taking a 8 000 units PCTC for example,a global finite element model of the whole ship was generated using the MSC/PATRAN software. The loading was based on the rules of NK classification society. Finally the result about racking strength was got. It is helpful to the direct calculation of racking strength of large-scale PCTC.
