摘要
轮毂轴承的寿命和损伤是直接影响汽车寿命和安全性的重要因素之一。本文对第三代轮毂轴承的旋转弯曲疲劳寿命进行预测,首先应用ABAQUS进行动力学有限元仿真,其次用nCode寿命分析软件得出模型的寿命云图预其测疲劳寿命。然后用旋转弯曲疲劳试验机进行试验,分析试验数据,以此验证旋转弯曲疲劳寿命预测模型的可行性。最后,对试验结果进行可靠性分析,以可靠性函数图评估预测结果的可靠度。
The life and damage of the wheel bearing are one of the important factors that directly affect the life and safety of the car.In this paper,we predict the rotating bending fatigue life of the third generation hub bearing.First,ABAQUS is used to perform dynamic finite element simulation of the hub bearing.Secondly,nCode life software is used to analyze and obtain the model life cloud to predict the fatigue life.Then we use a rotating bending fatigue testing machine to test and analyze the test data to verify the feasibility of the rotating bending fatigue life prediction model.Finally,the reliability analysis of the test results is carried out,and the reliability of the prediction results is evaluated by the reliability function graph.
