摘要:
高速列车刚柔耦合振动会引起车下悬吊设备的剧烈运动。介绍了高速动车组车辆悬吊设备以及质量调谐吸振理论。根据试验数据，分析了构架振动响应、车下设备振动响应，以及不同车速和线路对车下设备振动响应的影响。结果表明：正常路段构架横向振动加速度振动幅值较小，而蛇形激励路段构架横向振动主频为7.4 Hz。在振动水平正常时段，设备振动显著大于车体振动，设备频域振动特征主要为高频磁致振动，设备15 Hz以上的高频振动均未传递至车体。转向架蛇行激励时段，辅助变流器和车体耦合振动频率为7.6 Hz，设备和车体振动相位基本相同。运行速度增大时，车下设备振动增强，线路条件对车下设备振动也有重要影响。
Abstracts:
The rigid-flexible vibration of high-speed trains will cause violent movement of the vehicle suspension equipment. In this paper, the vehicle suspension equipment of EMU and the mass tuning vibration absorption theory are introduced. According to the test data, the vibration responses of the frame and the vehicle suspension equipment, the effects of different speed and lines on the vibration response of vehicle suspension equipment are analyzed. The results show that the lateral vibration frequency of the frame is smaller on normal line, it is 7.4 Hz while on hunting excitation line section. During the normal vibration times, the equipment vibration is significantly larger than that of the vehicle body, the vibration characteristics of the frequency domain of the equipment is mainly high-frequency magnetic vibration, but the high-frequency vibration of the equipment above 15Hz is not transmitted to the vehicle body. During the hunting excitation time of the bogie, the resonance vibration frequency of the equipment and the vehicle body is 7.6 Hz, the vibration phase of the equipment and the vehicle body are basically the same. When the running speed increases, so does the vibration of the suspension equipment, which indicates that the line condition has an important influence on the vibration of the suspension equipment.
