本文利用目前主流风电机组塔架的实测数据，基于振幅衰减速率计算阻尼比，给出了几个主流机型的实测阻尼比的值0.001-0.003，并依此认为目前风电机组仿真设计时选取的0.005的阻尼比偏大，可能存在安全隐患。%Tis paper used feld data of wind turbine towers to give the values of the damping ratio of some widely used wind turbines. Te measured damping ratio is between 0.001 and 0.003 which is computed according to the decay rate of vibration amplitude, and therefore the damping ratio of 0.005, which is commonly selected for today's simulation design of wind turbine, is too high, and this selection will lead to potential safety hazard.
