摘　　要：以某型10000 TEU集装箱船为例,针对不同上层建筑布置形式,采用有限元法进行全船的振动计算和评估,着重讨论了单岛式和双岛式上层建筑布置形式对船体和上层建筑本身固有频率、振动模态的影响,以及上层建筑在螺旋桨和主机激振力作用下的振动响应差异。该研究方法与结论对于实船设计有一定的借鉴意义。Single island design and twin island design are two typical design concepts for very large container vessel. Taking a typical 10 000 TEU container vessel for instance,the global vibration is calculated and evaluated by finite element method according to different superstructure arrangements. Based on single island design and twin island design arrangements for superstructure,this paper discusses their different effects on natural frequency and vibration mode of the hull and the superstructure, and their different forced vibration responses under the exciting forces or moments induced by propeller and main engine.
