摘　　要：在边界层风洞中对转动状态下的风力机模型进行了测力天平试验,研究了A、B两类地貌,0°桨距角,0°风向角时,风力机轮毂处两个轴向的风力系数,脉动风力功率谱和相干函数。结果表明:随着风轮转速的均匀增大,两个轴向的平均、脉动风力系数呈现出非均匀增大的现象;风轮转速为300rpm时,在折减频率为4Hz、6Hz处分别出现了风轮转动、天平-模型共振引起的谱峰。Wind turbine model in rotating state is performed in a boundary layer wind tunnel based on the force balance,researched A,B two types of landform, the blades pitch angle was 0°,the wind angle was 0°,two axial wind coefficients,wind power spectrum and coherent function at the hub of a wind turbine.The results show:with the uniform increase of wind wheel speed, the average and fluctuating wind coefficients of the two axes increase unevenly;When the rotation speed of the wind wheel was 300rpm, spectral peaks caused by wind wheel rotation and balance-model resonance appeared at the reduction frequency of 4Hz and 6Hz.
