摘　　要：风力发电机的碳管是叶尖扰流器和叶片主体的连接轴,现场维护工作中发现风力机气动刹车的碳素纤维管失效事故日益增加。从理论上调查碳管折断的影响因素,并通过GH Bladed对一台800kW的发生过失效事故的机型进行验算,验算结果证明,动态失速和叶尖扰流器的转动速度是主要的影响因素。Carbon shaft is the connecting shaft between tip flow-baffle device and the main body of wind turbine blade. Failure accident of the carbon shaft is found more and more frequent in maintenance jobs when air braking running. Research the cause of the failure in theory and calculate a wind turbine rated power 800 kW with the GH Bladed, and found that the dynamic stall~ and rotating speed when air brake running are main infuencing factors.

关 键 词：叶尖扰流器 动态失速 碳管
