摘要
城轨车辆在运行过程中存在着不同程度的振动,为了避免车身与车辆其他部件发生共振,因此要对车辆车体进行模态分析。文中主要建立了城轨车辆有限元模型,然后设计了模态分析工况,在A N SY S中进行了模态分析。结果证明,车体与车辆其他主要部件不会发生共振。
Urban rail vehicles have different degrees of vibration during running. The modal analysis of the vehicle body must be carried out to avoid resonance among vehicle body and other parts. Then the finite element model of urban rail vehicle is established. The modal analysis cases are designed,modal analysis is carried out. The results show that there is no resonance among vehicle body and other major components.
