摘要:
以国产首制大型邮轮为例,围绕其支柱的设计流程,从支柱的布置、设计载荷、规范设计和全船有限元分析等4个方面进行分析,总结该类船型的支柱设计特点。在规范计算中,主要考虑规范平均载荷和局部集中载荷2种情况下受压支柱的屈曲强度;在有限元分析中,主要考虑规范平均载荷与船体梁变形共同作用下支柱的屈曲强度和受拉支柱的屈服强度。通过全船有限元分析验证该设计满足要求,受拉支柱主要出现在艏部、艉部和上层甲板。研究成果及其实践可为后续类似船型的支柱设计提供参考。

Abstract:
The first domestically produced large cruise ship is taken as the example to analyze the design process of cruise ship pillars from four aspects of pillar layout, design load, standard design, and full ship finite element analysis. Meanwhile, the characteristics of pillar design for this type of ship are summarized. In rule calculations, the buckling strength of the compressed column is mainly considered with two conditions of the average load and the local concentrated load. In finite element analysis, the emphasis is on the buckling strength of the column and the yield strength of the tensile column under the combined action of the standard average load and the deformation of the hull beam. The finite element analysis of the entire ship has verified that the design meets the requirements, and the tension pillars mainly appear at the bow, stern, and upper deck. The research results and their practice can provide reference for the pillar design of similar ship types in the future.
