英文摘要	Aiming at the interference between the blade and tower caused by the vibration of flexible blade which will cause the fatigue failure of blade root, the interaction among the blade and the main shaft as well as its bearings were discussed. This paper proposed a simulation method based on multibody system dynamics theory. It was used to calculate the dynamic response of rigid and flexible coupling of a multibody subsystem that is composed of the wind wheel, the main shaft and its main bearing of horizontal wind turbine. The stiffness, damping, gap, flexible deformation and wind shear effects of main bearing are all considered in this model. To verify the effectiveness of this method, the dynamic performance of a 1.2 MW wind turbine was calculated and the wind turbine stands in a wind farm in the Hexi corridor of Gansu Province, China. The simulated results showed that spindle speed and aerodynamic forces imbalance of blade have an obvious effect on the stability of the shaft system. The vibration characteristics of shaft also have a strong correlation with bearing clearance. The root of blade appears alternating moments and the tip of blade emerges cyclical displacement. That there is just a slight deviation between this result and that obtained by standard analysis software Bladed confirmed the effectiveness of this method. © 2018, Editorial Board of Acta Energiae Solaris Sinica.
