摘　　要：随着全球航运规模的进一步扩大,集装箱船的大型化发展成为必然趋势,超大型集装箱船的船型特点导致船体结构遭受更严重的波激振动和砰击颤振作用,对船体结构疲劳强度产生较大影响。根据中国船级社规范和相关要求,基于三维线性/非线性水弹性理论,采用专用的三维水弹性计算软件,对一型超大型集装箱船开展波激振动和砰击颤振下船体结构疲劳强度直接计算评估和影响分析。分析结果表明,相关计算流程、算例和结论可为其他大型船舶在波激振动和砰击颤振下船体结构疲劳强度评估提供参考。With the further enlargement of global shipping, the large-scale development of container ships becomes an inevitable trend. The characteristics of ultra large container ships cause more severe springing and whipping to the hull structure, which has a greater impact on the hull structural fatigue strength. According to the Rule and Guidelines of China Classification Society and the three-dimensional linear/nonlinear hydro-elasticity theory, the special three-dimensional hydroelastic calculation software is adopted to directly calculate, evaluate and analyze the fatigue strength of an ultra large container ship under springing and whipping effects. The analysis results show that the relevant calculation processes, examples and conclusions can provide reference for the fatigue strength evaluation of hull structures of other large ships under springing and whipping.
