摘要: 設計了一種十輻Y 字型輪轂車輪并運用SolidWorks 建立三維模型, 分析并計算車輪的受力情況作為邊界條件, 將模型
簡化后導入ANSYS Workbench, 利用CAE 分析技術對輪轂的整體結構、強度等方面進行了研究。經過載荷計算和有限元分析發現
輪輻根部的連接處是最容易出現疲勞的部位, 其次是螺栓孔和中心孔由于在轉動過程中經常受預緊力和彎矩也很容易出現疲勞。
在改進輪轂結構時, 可以在螺栓孔之間安置徑向加強筋或者增加輪輻的厚度來提高輪轂的疲勞壽命, 經分析驗證了該設計方案的
可行性。為后續的進一步優化改進及模態分析、疲勞分析提供參考。

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.
