摘　　要：基于ABS规范,采用MD/Nastran有限元分析软件建立细化有限元模型,结合惯性释放技术,对万箱级集装箱船上甲板机舱前端及起居室后端椭圆形舱口角隅疲劳强度进行评估,并对起居室后端舱口角隅结构采取4种可行的优化措施以改善该处的疲劳强度。Based on ABS rules and the inertia relief method, the fatigue strength of elliptical hatch comers before engine room and after accommodation in container ship over 10 000 TEU was analyzed by MD/Nastran, with a detailed finite element model for the fatigue assessment area. And four kinds of new hatch corners were applied to improve the fatigue strength of hatch comer after accommodation.
