摘　　要：从载荷计算、结构应力计算、累计损伤计算等方面研究了适合于小水线面双体船疲劳强度评估的简化方法,并以某小水线面双体船为例进行了双体船疲劳强度评估简化方法的分析。结果表明,与横浪状态相比,迎浪和斜浪状态下的累积损伤较小,可以忽略。文中所述的简化方法对小水线面双体船的疲劳评估具有很好的应用性,所得结论对小水线面双体船的疲劳评估具有参考意义。The simplified method for the SWATH＇s fatigue strength evaluation was studied in terms of the load calculation,the structural stress calculation and the accumulative damage calculation.And one SWATH was chosen as example to study the simplified method of fatigue strength evaluation.The experimental results show that the cumulative damages in head sea and oblique sea are smaller than head sea,even can be ignored.The simplified fatigue assessment method described will have very good application,and it gives an important reference for SWATH＇s structure fatigue assessment.
