摘要
利用有限元分析软件MSC.Patran/Nastran对某铝质穿浪双体船首部焊接拖桩结构强度进行了分析和评估,得到了拖桩及其连接结构的详细应力分布情况,并根据分析结果提出了结构加强方案。本文可为其它类似拖桩结构强度有限元分析及结构优化设计提供一定的参考。
The analysis and assessment of structural strength of fore welding towing post in an aluminum wave-piercing catamaran is carried out by the finite element analysis software MSC.Patran/Nastran, the detailed stress distribution of the towing post and its attached structure is given and the structure strengthening scheme is provided based on the analysis results. This paper can provide some references for finite element analysis and structure optimized design for the other similar towing posts.
