| 摘 要： | 对于集装箱船而言,货舱角隅处一般存在结构形式的突变,在船体梁发生弯曲、扭转变形时,角隅承受着较大的弯曲正应力及翘曲应力,存在较严重的疲劳问题。本文以MARIC设计的某20000 TEU级超大型集装箱船为例,介绍了货舱内20 ft角隅、箱角角隅及舱口角隅的优化设计思路,通过有限元方法验证了优化方案的有效性。

| Abstract: | For container ships,big bending normal and warping stress due to the hull girder bending and torque will occur at the cargo hold corner and the fatigue strength is critical for such corner.This paper introduced optimized approach for the hatch corner and verified the optimized scenario by FEM analysis. |
