基于ANSYS的某汽车悬架有限元分析
|
摘要
采用某麦弗逊悬架参数,建立悬架系统的三维模型。利用ANSYS Workbench有限元分析软件对悬架进行了三种工况下的静力学分析,得出悬架的强度和刚度特性,并对悬架有限元模型进行了模态分析,将计算得到的悬架固有频率与汽车受到的其他激励频率进行对比,评价该悬架是否具有避开与车辆其他系统产生共振区域的性能,为今后的悬架设计提供了一定的理论基础。
The model of suspension system was established based on the parameters of McPherson. The static analysis of suspension under three working conditions was carried out using ANSYS Workbench,and the strength and stiffness characteristics of suspension were obtained. The modal analysis of the suspension model was carried out,and the calculated natural frequencies of the suspension were compared with excited frequencies of the vehicle to judge whether the suspension will produce resonance. It provided a theoretical basis for future suspension design.
