对某豪华邮轮进行振动特性分析，采用固有频率筛选法评估局部结构固有频率是否有足够的频率储备，采用有限元法计算得到其船体梁总振动固有频率和强迫振动响应。对不满足相关要求的船体结构区域，提出最佳振动控制方案，使豪华邮轮的振动水平满足舒适性要求。对大跨度舱室的立柱进行设计，在满足结构强度和振动控制要求的前提下提升旅客的舒适性体验。该邮轮振动特性分析中使用的方法及得到的结论，可为同类型船舶的振动预报和控制提供参考。
Vibration characteristics of a cruise ship are analyzed, using natural frequency screening method to assess whether natural frequencies of local structures have sufficient frequency reserves, and using finite element method to calculate natural frequencies of the hull girder and forced vibration responses. The optimal vibration control measure is proposed for ship structure areas that do not meet relevant requirements, and make the vibration level of the cruise ship meet the comfort requirements. Pillars in large span cabins are designed to enhance the passenger’s comfort experience while meeting the requirements of structure strength and vibration control. Methods used and conclusions obtained in the vibration characteristic analysis of the cruise ship can provide references for the vibration prediction and control of similar ships.
