摘　　要：以内河典型水泥运输船为例,应用有限元法计算水泥储罐所受应力,找出结构危险点,进而分别运用S-N曲线法、经典断裂力学方法、有限元法对储罐的疲劳寿命进行评估,分析结果对了解储罐疲劳寿命及改进该型船舶的设计提供有益参考.In this paper, setting a typical inland river cement ship as an example. The stress distribution of the cement deposited tank is calculated using FEM method to identify structural danger point. Then S-N design curve method, classical fracture mechanics method and FEM method are used to do the assessment of fatigue life of the tanks. The results provide a useful reference to improve the design technology of this type ship.
