摘要
Abstract
Pitch beating 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 beating considering combined loads is proposed.The deformation of a typical pitch beating 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.关键词
