某汽车差速器齿轮的强度分析及疲劳寿命预测
A Car Differential Gear Strength Analysis and Fatigue Life Prediction
摘要
Abstract
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.关键词
