一种新的四连杆悬架刚柔耦合模型

A New Four-link Suspension Rigid-flexible Coupled Model

在动力学仿真软件Adams/View模块中建立了四连杆后悬架模型,该模型考虑了轮胎的特性对悬架定位参数的影响。分析了四连杆后悬架的结构及杆件刚度对悬架定位参数的影响,并求出纵拖臂的自由模态,生成纵拖臂柔性体模型后替换原来的刚性杆件,建立悬架的刚柔耦合模型。

The four-link rear suspension model is established in the view environment of dy- namic simulation software ADAMS, which takes into account the influence of the tire characteristics on the alignment parameters. The structure style and the links＇influences on the alignment parameters of a four-link rear suspension are analyzed in this paper. The free mode of the longitudinal trailing arm is analyzed, and the flexible body model of longitudinal trailing arm is generated as to replace the rigid one. Thus a rigid-flexible coupled model of the suspension is established.
