Abstract In view of the complexity of the traditional fatigue life calculation method of double row self-aligning roller bearing, a numerical simulation method for predicting the fatigue life of double row self-aligning roller bearing based on finite element software is proposed to evaluate the fatigue life of double row self-aligning roller bearing used in fan main shaft bearing. According to the relevant parameters of the fan and the bladed software, the limit load data table of the unit in the center of the impeller hub is obtained, and the axial and radial limit load values are selected for the finite element analysis of the double row self-aligning roller bearing. Finally, the fatigue life of spindle bearing is evaluated under 11 representative working conditions. The results show that the fatigue life calculated by von Mises stress combination and Goodman average stress correction method and the life calculated by the correction formula are consistent with the 20-year service life of wind turbine, which shows the feasibility of this method.
