本文基于某漂浮式缩尺样机实际工程项目，采用时域分析方法对该半潜式浮式风机平台瞬态响应进行数值仿真计算，深入研究了系泊长度以及配重块重量对锚泊系统导缆孔预张力和浮式平台运动响应的影响规律。结果表明，浮式平台的纵摇、纵荡和垂荡的响应幅值随着系泊长度的增大先增大后减小；增加配重块的重量，会导致平台的纵荡和垂荡先增大后减小，纵摇先减小后增大；当同时改变系泊长度和系泊配重块重量时，配重块重量不影响系泊长度对浮式平台运动响应的变化规律的影响。

Based on an actual engineering project involving a floating scale prototype， this article employs a timedomain analysis method to numerically simulate the transient response of a semi-submersible floating wind turbine platform. It extensively investigates the influence of varying anchor chain length and counterweight mass on the pre-tension of the mooring system and the motion response of the floating platform. The results indicate that the amplitude of pitch， heave， and surge responses of the floating platform initially increases and then decreases with an increase in mooring length. Increasing the mass of the counterweight leads to an initial increase and subsequent decrease in pitch and heave responses， while the surge response initially decreases and then increases. When simultaneously changing both the mooring length and counterweight mass， the counterweight mass does not affect the variation pattern of platform motion response caused by mooring length.
