摘　　要：以白云鄂博地区拟建的某2 MW钢管混凝土格构式新型风力发电机塔架为研究对象,采用Davenport脉动风谱基于谐波合成法模拟白云鄂博地区脉动风速时程,运用有限元软件对风力发电机塔架进行风致响应分析。结果表明:钢管混凝土格构式风力发电机塔架风振响应显著,受脉动风影响很大;按照现行规范对钢管混凝土格构式塔架风振系数进行计算将造成较大误差。With a 2 MW lattice type wind turbine tower made of concrete-filled steel tubes(CFST)in Bayan obo area of Inner Mongolia as the research object,using the Davenport wind spectrum based on harmonic synthesis simulation of fluctuating wind speed data in this area,the wind-induced response of the wind turbine tower is analyzed by means of the finite element software.The results show that the wind vibration response of the lattice type wind turbine tower of CFST is greatly affected by the fluctuating wind;the wind vibration coefficient of the CFST tower calculated according to the current specification will cause large errors.
