摘　　要：利用抗疲劳设计优化方法对油船、散货船和集装箱船的典型结构节点进行分析,梳理若干典型节点的抗疲劳设计标准。部分典型结构节点如舱口角隅等的抗疲劳设计标准可作为疲劳校核的等效方法。在设计时,通过疲劳强度计算改进结构详细节点的设计,以保证船体构件的疲劳寿命能满足要求。Anti fatigue design method is adopted to analyze the typical structure joints of oil tankers, bulk carriers and container ships to deduce the anti fatigue design standards. Some standards such as on hatch corner can be used for equivalent method of fatigue assessment. In the design stage, structure joints can be optimized by fatigue analysis, so as to guarantee that the fatigue life of the hull structures could meet the requirement.
