摘要
简要介绍了船舶结构疲劳强度谱分析法原理,基于DNV规范,应用SESAM软件对一实船典型节点的疲劳强度进行分析校核。介绍了运用SESAM软件进行谱分析法疲劳强度评估的过程及注意事项,有关结论可供相关设计人员参考。
This article introduced the spectrum analysis theory of structural fatigue strength for seagoing vessels. Based on DNV rules, structural fatigue strength of typical details of an actual vessel was analyzed and verified by means of the software SEASAM. Summarizing the analyzing procedures and technical key points of the spectrum analysis method, this article could serve as reference for fellow designers.
