摘　　要：选择沪东中华造船(集团)有限公司即将建造的8530TEU集装箱船船舯N o.5货舱区上甲板角隅为分析对象,采用半概率的设计波法,分别计算得到在1-0 4超越概率下满载状态和压载状态时该角隅边缘最大应力范围;然后根据挪威船级社规范,基于S-N曲线和Pa lm gren-M iner线性累积损伤理论计算该角隅的疲劳累积损伤度,并进行了疲劳寿命预估;最后,讨论了不同波浪散布图的选取对该角隅疲劳寿命计算的影响。Fatigue life of upperdeck hatch corners in the midship of an 8530TEU container ship is prediction in this paper. Firstly, hatch corners at No. 5 cargo hold are finely meshed in the global structural model. The maximum stress ranges respectively in full loaded condition and in ballast loaded condition can be calculated from the structure analysis of this new global model based on design wave method. Secondly, the accumulated fatigue damage is calculated according to the Miner＇s rule of linear damage accumulation with S-N＇s curves, and fatigue life is predicated. Finally, the influence of different seatter diagrams on the fatigue life of this structural detail is also discussed.
