英文摘要	To investigate the phenomenon that wind turbine blades are prone to fatigue failure, the 1.5 MW wind turbine blades are regarded as object, the loads and stresses of dangerous cross section are calculated by using GH Bladed and ABAQUS software, respectively. Based on the multi-axial fatigue theory of composite materials, the multi-axial fatigue life of wind turbine blades under the rated wind speed is analyzed, and the results of multi-axial fatigue life and uniaxial fatigue life are compared. The results shown that the traditional uniaxial fatigue life model may overestimate the fatigue life of wind turbine blades, and the multi-axial fatigue life analysis method can accurately estimate the fatigue life of wind turbine blades. Therefore, in this paper, the proposed method has some guiding significances for the evaluation of multi-axial fatigue life and reliability design of wind turbine blades. © 2020, Editorial Board of Acta Energiae Solaris Sinica.
