电动汽车同轴直联车桥强度分析及疲劳寿命预测
Strength analysis and prediction on fatigue life of coaxial straight axles on the electric car
同轴直联车桥是纯电汽车上的主要承载件与传力件，其强度是否可靠直接决定了整车的安全性。先利用Solidworks对同轴直联车桥零部件进行三维建模，后导入ANSYS Workbench，对车桥进行有限元分析及疲劳寿命预测。分析和预测了同轴直联车桥在最大铅垂力典型工况下的结构强度和疲劳寿命。结果表明，仿真结果均满足设计要求，为实际生产提供理论依据。
oaxial straight axles the main bearing and transmission parts on the electric car, The strength of coaxial straight axles is reliable directly determines the safety of the vehicle.Firstly, the three-dimensional model of the front axle was set up in Solidworks, the model was imported into ANSYS Workbench.Finite element analysis and fatigue life prediction of axle.The structural strength and fatigue life of the coaxial straight axle under the typical conditions ofthe maximum vertical forceare analyzed and predicted.The results show that coaxial straight axles could meet the requirements. It would provide a theoretical basis for the practical production
