摘    要:垂荡阻尼板是一种增加Truss spar阻尼的结构形式,它可以通过增加平台的阻尼和附加质量,从而达到减小其垂向运动的目的.为了研究垂荡板的水动力,进行了三角形垂荡板在单板和双板两种情况下的强迫振荡试验.将试验结果用Morison公式进行了分析,给出了垂荡板在较大Re和Kc时的惯性力系数和拖曳力系数,并探讨了板间距对水动力系数的影响,得出了理想的板间距.对阻尼板的设计具有一定的实用意义.

关 键 词:垂荡阻尼板  水动力  Morison公式  惯性力系数  拖曳力系数

Abstract:Heave damping plates are structures used to increase the added mass and damping of truss spar. Thus the heave motion of spar can be reduced. In order to study the hydrodynamics of heave plates, the forced oscillation tests on a single plate arrangement and double plate arrangement were carried out. The plates are all triangular. The drag coefficients and inertia coefficients versus Re and K c were given through the analysis of experimental data by using Morison formula. The double plate arrangement is involved and the effects of space between the two plates on hydrodynamic coefficients were discussed, and the best gap was obtained.
Keywords:heave plate  hydrodynamics  Morison equation  inertia coefficient  drag coefficient
