摘要： 为预测侧向加载工况驱动桥轮毂轴管的应力分布，针对轮毂轴管进行了受力分析，建 立了力学模型，并综合几何和力学分析，确定了轴承滚动体与滚道之间的接触载荷；将该载 荷以线载荷的形式施加到轴承内圈滚道上，建立了轮毂轴管的有限元模型；基于该模型获得 了轮毂轴管的应力分布，并基于定性、定量方法验证了该有限元模型。结果表明，所给出的 轮毂轴管有限元建模方法较简化方法，获得的应力分布更为合理，较大的应力位于结构刚度 变化大的区域，即螺纹根部、轴承安装轴颈圆角、轮毂轴管根部圆角，研究结果可用于指导 轮毂轴管设计。

Abstract: To predict the stress distribution of the driving axle hub shaft under lateral loading conditions, a force analysis is conducted on the hub shaft, a mechanical model is established, and the contact load between the bearing rolling element and the raceway is determined by combining geometric and mechanical analysis. The load is applied to the inner race of the bearing in the form of a linear load, and a finite element model of the hub shaft is established. Based on this model, the stress distribution of the hub shaft is obtained, and the finite element model is validated using qualitative and quantitative methods. The results show that the finite element modeling method for the hub shaft provided is simpler than the simplified method, and the stress distribution obtained is more reasonable. The larger stress is located in the area with significant changes in structural stiffness, as well as at the root of the thread, the fillet of the bearing installation journal, and the fillet of the hub shaft root. The research results can be used for the design of the guide hub shaft.
