摘要: 设计了一种十辐Y 字型轮毂车轮并运用SolidWorks 建立三维模型, 分析并计算车轮的受力情况作为边界条件, 将模型
简化后导入ANSYS Workbench, 利用CAE 分析技术对轮毂的整体结构、强度等方面进行了研究。经过载荷计算和有限元分析发现
轮辐根部的连接处是最容易出现疲劳的部位, 其次是螺栓孔和中心孔由于在转动过程中经常受预紧力和弯矩也很容易出现疲劳。
在改进轮毂结构时, 可以在螺栓孔之间安置径向加强筋或者增加轮辐的厚度来提高轮毂的疲劳寿命, 经分析验证了该设计方案的
可行性。为后续的进一步优化改进及模态分析、疲劳分析提供参考。

Design of Aluminum Alloy Ten-spoke Y-shaped Wheel and Finite Element Analysis

(Automotive Engineering Department, Chengde Petroleum College, Chengde Hebei 067000, China) Abstract: A ten-spoke Y-shaped wheel was designed. The three-dimensional entity model was simplified and imported into ANSYS
Workbench, the overall structure and static strength of the wheel and so on were studied by using CAE analysis technology. After load calculation
and finite element analysis, it is found that the joint of the spoke root is the most prone to fatigue, the bolt hole and the center hole are also
prone to fatigue due to the preload and bending moment during the rotation. In the structure, radial stiffeners may be placed between the
bolt holes or the thickness of the spokes may be increased to improve the fatigue life of the hub, the feasibility of the design scheme is verified
by analysis. It provides reference for subsequent further optimization and improvement, modal analysis and fatigue analysis.
Keywords: Aluminum alloy wheel; Structural design; FEM; Strength analysis
