摘要
根据汽车振动及有限元理论,建立了桥壳动态分析的力学模型,在计算机上利用先进的有限元分析软件ANSYS,建立桥壳的有限元动态模型,并进行了有限元的模态分析和瞬时动态分析。在模态分析中,桥壳有限元模型的固有频率及振型的计算结果与试验结果吻合较好;在瞬态分析中,可确定桥壳上各点承受随时间变化载荷的位移及应力等动态响应,从而完善了车桥的有限元动态设计方法。
The dynamic performance of driving axle housing was studied in this paper. According to the principle of automotive vibration and finite element, the finite element dynamic model of automotive driving axle housing was created in the computer. Based on this model, the modal analysis and transient dynamic analysis was carried out.
