摘　　要：用ANSYS软件对桑塔纳轿车前轮毂轴承进行有限元分析 ,确定合理的凸度形式及滚子与滚道的最佳凸度匹配关系 ,给出了滚子、内圈滚道最佳凸度控制方程。结果表明 :凸度形式及滚子与滚道的凸度匹配关系对轴承的载荷分布和承载能力有显著影响 ,最佳凸度控制方程对改进轮毂轴承凸度设计具有重要的指导意义。The crowning of the front hub bearings of Santana car is analyzed by using ANSYS finite element software,and the proper crowning form and optimal crowning match relation between roller and raceway are determined.The optimal crowning control equations of roller and inner raceway is given.The results show that the crowning match relation between roller and raceway has an important influence for load distribution and capacity of the bearing,the optimal crowning control equations has mainly guiding meaning to improve crowning design of hub bearing.
