  • 摘要: 研究船舶总振动时,单体船及双体船的附连水质量已经有了计箅公式,但是针对多体船(如三体船)的总振动,国内外的研究甚少。随着三体船的需求增加,需在设计时对其总振动进行预报。正确预报三体船的振动,需正确计算参与振动的附连水质 量.介绍采用CFD软件Fluent数值计算三圆柱体附连水质量的简便方法,通过计算得出三圆柱体附连水质堪随间距变化的规律,得出三体船垂向振动的单位长度的附连水质量,为三体船的总振动计算提供了依据.
    Abstract: Until now, there have been calculation formulations for added water mass of monohull and eatamaran in the research of ship overall vibration. But for the overall vibration of muhihull, such as trimaran, there has bee n little research domestically and overseas. With the increasing need of trimaran, its overall vibration should be calculated in the process of design. And the proper calculation of its overall vibration is in need of its added water mass. A simple method for calculating the added water mass of ternate cylinders by means of the CFD software Fluent is put forward in the paper. From the calculation, the change of their added water mas s with their distance is obtained, and the added water mass of unit length of the trimaran vertical vibration is also obtained, which provides foundation for the trimaran overall vibration.
