摘　　要：以3600 t起重船为研究对象,分析海流载荷对正常工作起重船的影响。根据给定参数,采用不同方法计算起重船横向、纵向冲击力,并对计算结果进行了比较。最后利用水动力分析软件AQWA进行验证,对起重船进行频域线性水动力分析,得到该起重船在遭遇角分别为0°和90°时的船体面板应力变化情况,为3600 t起重船的海流载荷计算提供可靠的理论依据。Taking a 3600 t crane ship as the research object,the influence of current load on normal working crane ship was analyzed.Based on given parameters,different methods were applied to calculate the transverse and longitudinal impact force of the crane ship,and calculation results were compared.Finally,the hydrodynamic analysis software AQWA was used to verify and analyze the frequency domain linear hydrodynamic force of the crane ship,and stress changes of the hull panel of the crane ship were obtained when the angles are 0 degree and 90 degree respectively,which provides a reliable theoretical basis for the calculation of the current load of the 3600 t crane ship.
