当前，海上浮式风电平台减荡的基础方式是采用立柱-减荡板组合装置。结合浮式基础的运动分析发现，减缓垂荡运动是保证平台稳定性的一个重要方向。本文以单浮体减荡板为研究对象，分析减荡板的不同开孔形式对水动力特性的影响。采用数值计算和试验验证相结合方式，在不同工况下对各种倒角开孔形式进行垂向力、附加质量系数和阻尼系数等水动力参数进行规律分析，得出开孔对垂向减荡效果有益，并且随着开孔倒角角度变化，单浮体减荡装置的水动力特性规律出现明显改变。
At present, the combination device of pillar and slab is often used to reduce the vibration of offshore floating wind power platform foundation.Through an analysis of the motion of floating foundations, it is found that reducing heave motion is a crucial aspect of ensuring platform stability. This paper focuses on the single floating body damping plate, analyzing the impact of different hole designs on its hydrodynamic characteristics. By combining numerical calculations with experimental validation, vertical force, added mass coefficient, and damping coefficient under different conditions are systematically analyzed for various chamfered hole designs. The results indicate that perforation improves the heave damping effect, and as the chamfer angle of the hole changes, the hydrodynamic characteristics of the single floating body damping device exhibit significant alterations.
