摘　　要：利用ANSYS有限元软件,对正常运行工况和危险工况下的低风速风力发电机轮毂进行了有限元分析,得到了轮毂的应力分布状况。利用ANSYS的Fatigue模块对轮毂进行了疲劳寿命计算,并进行了强度校核,危险工况下的应力分析表明,轮毂满足强度的要求,安全系数为2.1,轮毂的疲劳寿命为8.8 a。The static strength analysis of low wind speed turbine hub was calculated under the normal and maximum loads by ANSYS finite element analysis software.The stress distribution of hub was obtained. The strength of hub was checked up and fatigue was calculated by using fatigue module of ANSYS .The results of maximum loads indicated that the hub was satisfied for strength requirement, and the safe coefficient was 2.1 and the fatigue life of hub was 8.8 years.
