The lightweight of axle hub has been recognized as a typical representative of reducing the quality of vehicles for energy saving and emission reduction. Therefore, a modeling analysis and lightweight design based on ANSYS for axle hub is proposed. Firstly, design dimensions and structural parameters of axle hub are modeled. The hub model is imported into workbench software to simulate the static analysis. The stress and deformation of the axle hub are obtained by mesh element division, boundary condition constraints and loading conditions, and the modal and fatigue strength of the hub are simulated to obtain the modal natural frequency and life data. Then, from the point of view of reducing the quality and safety of the hub, the structure of the hub is changed, the model is compared again, and the lightweight design scheme can be obtained. The results show that the weight of a hub decreases by 5.537% after lightening. This method can improve the structure, save materials, reduce production costs, and shorten the design cycle. This lightweight design method has important reference and practical significance for the lightweight design of axle wheels and similar products.

轴毂轻量化被认为是降低车辆质量以实现节能减排的典型代表。为此，提出基于ANSYS的轴轮建模分析及轻量化设计。首先，对轴毂的设计尺寸和结构参数进行建模。将轮毂模型导入Workbench软件中进行静态分析模拟。通过网格单元划分、边界条件约束和加载条件得到轴毂的应力和变形，并对轮毂的模态和疲劳强度进行模拟，得到模态固有频率和寿命数据。然后，从降低轮毂质量和安全性的角度出发，改变轮毂的结构，再次进行模型比较，可以得到轻量化设计方案。结果表明，轻量化后轮毂重量减轻了5.537%。这种方法可以改善结构、节省材料、降低生产成本、缩短设计周期。该轻量化设计方法对于车轴轮及同类产品的轻量化设计具有重要的参考和实际意义。
