摘　　要：本文采用数学建模的方法,引入四点接触球轴承套圈刚度矩阵,以此考虑结构刚度对四点接触球轴承内部载荷分布的影响。建立了四点接触球轴承的非线性位移和力学平衡方程,该方程可采用牛顿拉普逊方法迭代求解。以风力发电机组偏航变浆用四点接触球轴承为例进行了计算分析,验证了本文建立数学模型的计算快速性和精确性。In this paper, the stiffness matrix of four point contact ball bearing ring is introduced by mathematical modeling method, and the influence of structural stiffness on the load distribution of slewing bearing is considered. The nonlinear displacement and mechanical equilibrium equations of four point contact ball bearings are established, and the equations can be calculated by Newton-Raphson iteration procedure. Taking the four point contact ball bearing as an example, the calculation and analysis of the yaw and pitch bearing of the wind turbine are carried out, and the calculation speed and accuracy of the mathematical model established in this paper are verified.
