摘要

岩土阻尼对降低大直径单桩海上风电机组结构动力响应具有巨大潜力。然而,岩土阻尼的贡献尚不十分清楚,部分原因是缺乏在海上风电机组一体化时域分析中岩土阻尼的考虑方法。有学者通过在泥面配置阻尼矩阵实现了在一体化时域分析中考虑岩土阻尼,但由于水平和旋转自由度耦合,导致旋转阻尼系数计算存在问题。为此,提出一种改进型集中式阻尼方法：在单桩等效旋转中心处施加阻尼矩阵。等效旋转中心是单桩基础的“解耦点”,解决泥面刚度矩阵中水平和旋转自由度的耦合使得基于表观旋转刚度计算旋转阻尼系数变得困难的问题。首先推导桩-土相互作用系统的阻尼比及等效旋转中心位置的计算公式;然后通过在OpenFAST开发SoilDyn模块将该改进方法纳入海上风电机组一体化时域分析;最后,在相同荷载水平下,通过与分布式阻尼结果的对比验证改进型集中式阻尼方法的合理性。

Abstract

This paper proposes an improved centralized damping method： applying a damping matrix at the equivalent rotational center of the monopile. The equivalent rotational center serves as a "decoupling point" for the monopile foundation, addressing the coupling issue in the stiffness matrix at the mudline that complicates rotational damping coefficient calculations based on apparent rotational stiffness. First, the formulas for calculating the damping ratio of the pile-soil interaction system and the position of the equivalent rotational center are derived. Then, this improved method is incorporated into the integrated time-domain analysis of offshore wind turbines by developing the SoilDyn module in OpenFAST. Finally, the validity of the improved centralized damping method is verified by comparing it with distributed damping results under the same load conditions.
