摘　　要：　针对有些船舶如大型集装箱船的非直壁、船首大外飘等波浪载荷具有明显非线性,提出采用直接计算法进行疲劳强度分析,并提出了计算的一些具体内容和计算公式.计算结果表明,非线性波浪载荷对船体结构疲劳损伤分析具有重要影响.According to the facts that some ships such as contain ships with very large flare suffer the non-linear wave induced loads, a method of direct calculation for fatigue strength analysis of ship structures is put forward. In the analysis, the non-linear wave loads should be included. Calculation results show that nonlinear factors are important for fatigue strength analysis of ship structures.
