| Abstract: | 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. |
