| 摘 要： | 首先针对圆形实板以及不同透空率下垂荡板作受迫正弦振荡的水动力特性进行了数值模拟研究,得到垂荡板作正弦振荡的阻力和附加质量系数,进而分析得出透空率对垂荡板阻尼及附加质量的影响规律;其次比较了相同透空率情况下不同小孔数目对垂荡板水动力特性的影响,并比较了不同形状垂荡板的水动力特性;最后还对双板之间的间距进行了优化计算.在此基础上综合考虑垂荡板受迫振荡水动力特性,为深水Spar平台的垂荡板优化设计提供技术指导,使其能够有效地改善Spar平台的垂荡运动性能.

| Abstract: | Firstly, Hydrodynamic characteristics of circular heave damping plates with different porosity are studied and simulated.Numerical results of the resistance coefficients and added-mass coefficients are given,and the influences of the porosity on the resistance and added mass coefficients are also investigated.Secondly, the hydrodynamic characteristics of heave damping plates with various numbers of the holes and various shapes are compared at the same porosity.Finally, different distances between two heave ... |
