Method for determining position and polishing amount of variable-pitch bearing soft belt of wind turbine generator

A method for determining the position and polishing amount of a variable-pitch bearing soft belt of a wind turbine generator comprises the steps that a finite element model of a variable-pitch bearingconnecting system is set, and the deformation amount of a variable-pitch bearing under different limit loads and the deformation amount of the variable-pitch bearing under different fatigue loads arecalculated according to the model; and finally, the soft belt position and the polishing amount are determined according to the two sets of deformation amounts. The deformation of the bearing under the limit load and the deformation of the bearing under the fatigue load are calculated by establishing the finite element model of the variable-pitch bearing connection system, and the placement position of the soft belt and the polishing amount of the soft belt are determined by considering the deformation under two different loads, so that the obtained result is more reasonable. 一种风电机组变桨轴承软带位置及打磨量的确定方法，设置变桨轴承连接系统的有限元模型，根
