摘要
基于Ｓ－Ｎ曲线和Ｍｉｎｅｒ线性疲劳累积损伤原理，建立了运用谱分析法通过整船有限元分析进行船体结构疲劳可靠性分析的完整过程，并使用ＤＮＶ的ＳＥＳＡＭ程序系统，对一４５５００ｔ大型散货船的船体结构进行了疲劳可靠性分析．
Based on the Miner′s rule of linear damage accumulation with S N curves, a complete procedure for fatigue reliability analysis of ship full structures by using the spectral method is established. By employing the SESAM program system developed by DNV, a fatigue reliability analysis for a 45 500 tonne large bulk carrier is carried out by following this procedure.
