Abstract: Pitch bearing is a key component of wind turbine. The stress state and deformation of pitch bearing has major impact on operation safety of wind power system. A calculation model of pitch bearing considering combined loads is proposed. The deformation of a typical pitch bearing is calculated by using Newton-Raphson method. The stress distribution and deformation of pitch bearing are simulated by implementation of a finite element model in ANSYS. The results show that the theoretical calculation model is correct and has enough accuracy, which provides a simple calculation method in pitch bearing structural design.
