摘　　要：通过实测风场并结合分型维数构建湍流环境,分析风速、浪高和风浪错位角变化时对单桩式风力机的影响。研究发现,湍流风速变化对风力机影响最大,风速增加导致其纵荡、纵摇均值及幅值增加且波动剧烈。浪高对风力机影响较小,但随浪高增加,两方向变化频率增大,易引起额外疲劳载荷。风浪错位角在0°-180°之间变化时,平台运动的变化较缓;风浪同向时,平台受来流频率的影响较大;而风浪交错时,纵荡及纵摇均值略高于风浪错位均值。By combining the fractal dimension with wind field measurements,a turbulent envi-ronment was created to analyze the impact of varying wind speed,wave height,and wind-wave misalignment angle on a spar wind turbine.The study revealed that changes in wind speed had the greatest effect on the turbine,leading to increased surge and pitch with sharp fluctuations.Wave height had a lesser effect,but an increase in height led to higher frequency changes and additional fatigue loads.Wind-wave misalignment angle had a slower impact on platform motion when it var-ied between 0°-180°.In the same direction,the platform was more affected by the frequency of incoming current,while staggered wind-waves resulted in slightly higher mean values of surge and pitch compared to wind-wave misalignment.
