运用现代设计方法进行了某汽车差速器齿轮静强度分析和疲劳寿命预测。将几何模型导入HyperMesh中，利用壳单元和实体单元划分网格，并建立合适的MPC单元以方便载荷和约束的施加。根据齿轮的对称性，建立了行星齿轮和半轴齿轮单齿的有限元模型。利用有限元分析软件ANSYS进行行星齿轮和半轴齿轮静强度分析。分析结果表明所设计的齿轮能满足强度要求。基于齿轮有限元分析结果，利用疲劳分析软件MSC．Fatigue得出行星齿轮和半轴齿轮寿命云图及最低疲劳寿命，均满足寿命要求。

Modern design method is used for a car differential gear static strength analysis and fatigue life prediction. The geometric model is imported to HyperMesh, the shell element and entity unit are used for division grid, and proper MPC unit are established for load and constraint applied. According to the gear of symmetry, planetary gear and axle side gear single tooth finite element model are established. Using finite element analysis software ANSYS, planetary gear and axle shaft gear static strength are analyzed, and the results show that the designed gears can meet the requirements. Based on gear finite element analysis results, planetary gear and axle shaft gear life nephogram and minimum fatigue life are analyzed by using fatigue analysis software MSC. Fatigue. Both gears can satisfy actual life requirement.
