摘要

采用MacPherson四分之一汽车模型，采用刚体动力学与有限元分析相结合的非常规方法确定了悬架球接头的疲劳寿命。在本研究中，为了获得平顺性和球节点处的反作用力，将四分之一汽车模型置于国际标准组织(ISO)随机道路剖面中进行坑洼和减速带测试。在对三种平顺性进行分类后，对该模型进行另一次仿真，研究将球关节及其承窝作为柔性体的应力分布。最后，根据有限元分析结果，对各平顺性下的接头疲劳寿命进行了测量。研究结果表明，良好的平顺性对球接头部件的疲劳寿命有不利影响。采用ANSYS Workbench和CATIA V5进行建模和仿真。

Fatigue life study of suspension ball joints on the basis of ride quality

The MacPherson quarter car model was used to determine fatigue life of a suspension ball joint using a non-conventional approach which combined rigid body dynamics with finite element (FE) analysis. In this research, a quarter car model was subjected to International Standards Organization (ISO) random road profile with a pothole and a speed bump in order to obtain the ride quality and the reaction forces occurring at the ball joint. After classifying three ride qualities, another simulation was conducted on this model to study the stress distributions, in which the ball joint and its socket were treated as flexible bodies. Finally, based on the results of the FE analysis, fatigue life of the joint was measured for each ride quality. Based on the findings, it was concluded that a good ride quality has an adverse effect on the fatigue life of the ball joint component. ANSYS Workbench and CATIA V5 were used for modelling and simulation.
