1.6万标准箱集装箱船外飘砰击及结构强度计算研究

超大型集装箱船面临首部特殊型线与高航速所带来的不容小视的首部外飘砰击载荷作用。文中以1.6万标准箱集装箱船为例,首先基于时域Rankine源法计算集装箱船的非线性运动响应;然后预报首部区域发生外飘砰击的概率和砰击压力极值;最后考虑外飘砰击对首部局部区域的作用,对1.6万标准箱船的首部结构进行了有限元分析,评估船体结构承受外飘砰击载荷的能力,为首部结构设计提供参考依据。

Calcutation study of lfare impact and structural strength of 16 000 TEU container ships

Ultra-large container ships are facing to the noticeable bow flare impact effect due to special bow shape and high speed. Taking a 16 000 TEU container ship as an example, first, this paper calculates the nonlinear motion responses of this ship by time-domain Rankine source method. Second, it predicts the probability of the flare impact occurred in the bow area and the impact extremum. Finally, it carries out the FEM analysis of the bow structure with consideration of the ef ect of the flare impact on local area of bow, and evaluates the endurance of the ship structure, which can provide references for the design of the bow structure.
