摘　　要：以悬挂式单轨车辆转向架构架为研究对象,对悬挂式单轨车辆转向架构架的自由模态和约束模态进行了计算,并对其各阶模态下的固有频率和振型进行分析。结果表明:转向架在各阶模态对应的固有频率下的振型合理,各向刚度变化较小,可以满足构架上零部件正常工作环境的要求,转向架对车辆的平稳运行起到了重要作用。this paper,the bogie frame of suspension monorail vehicle is taken as the research object,the free mode and constrained mode are calculated,and the natural frequency and mode shape under each order mode are analyzed.The results show that the vibration mode of the bogie at the natural frequency corresponding to each mode is reasonable,and the stiffness variation in each direction is small,which can meet the requirements of the normal working environment of the components on the frame,and the bogie plays an important role in the smooth operation of the vehicle.
