| 摘 要： | 通过半解析法和有限元法对一艘2750TEU集装箱船进行了机舱、尾部及甲板室的局部振动预报，包括板格、筋和板架的首阶固有频率以及罗经甲板和舷侧板架的固有频率和振动模态。计算表明，2750TEU集装箱船的局部振动性能良好，满足亚临界动态设计的设计衡准。指出对采用低速机的船舶而言，用亚临界动态设计方法是可行的。

| Abstract: | In this paper, based on semi-analytic method and FEM, evaluations on local vibration analysis of a 2 750 TEU container vessel are studied. The 1 st natural frequency of the plate, stiffer and panel in engine room, aft part area and deckhouse are calculated as well as the natural frequency and vibration mode of compass deck. The results indicate that the local vibration characteristics of 2 750 TEU container vessel are satisfactory and meet the requirements of sub-critical dynamic design criteria. |
