摘　　要：为了确定主导超大型集装箱船强度评估的等效设计波,以一型2万箱级超大型集装箱船为对象,根据超大型集装箱船的结构特点,定制43个初始等效设计波,计算得到每个设计波下的全船结构应力结果,同时采用应力谱分析方法对整船典型位置及节点进行应力的长期预报,二者结果对比,筛选确定真正对超大型集装箱船结构强度评估起主导作用的10个设计波。To establish the equivalent design waves that dominate the strength assessment of ultra large container ship,a 20000 TEU container ship was selected as the research object.According to the structural characteristics of the ship,43 initial equivalent design waves were customized,and the stress results of the whole ship under each design wave were calculated.The stress spectrum analysis method was used to predict the long-term stress of the typical positions and nodes of the whole ship.Through the comparison of the two results,10 of the 43 design waves that really play a leading role in the strength of the whole ship structure were obtained.
