近年来，规范的更新和船东对舒适性要求的提升，船体振动问题愈来愈受到重视。本文采用有限元法从上层建筑整体纵向振动、船体梁总振动、局部结构振动3个方面对某型支线型冷藏集装箱船进行振动特性预报。针对不足的情况，提出改进方案，使振动水平能够满足相关标准的要求，探讨集装箱船早期设计阶段上层建筑整体纵向振动的预报方法。计算分析中获得的经验和结论，可供同类型船舶设计参考。
In recent years, as rules updating and the improvement of ship owner's requirements for comfort, ship vibration problem has been paid more and more attention. In this paper, the finite element method is used to predict the vibration characteristics of a feeder reefer container vessel from three aspects:the overall longitudinal vibration of the superstructure, overall vibration of hull girder and local structural vibration. For the situation of insufficient vibration characteristics, an improved scheme is proposed to make the vibration level meet the requirements of relevant standards. Besides, the forecast method of the overall longitudinal vibration of the container in the early design stage is discussed. The conclusions obtained in the calculation analysis can be used for the design of the same type of ship.
