对高温超导磁悬浮车辆系统的垂直振动特性进行了实验研究。在一定的悬浮间隙下，测量了不同外部激励频率下磁悬浮车辆系统的位移变化。当外部振动频率较低时，响应曲线的幅值变化较小。随着振动频率的增加，可以发现混沌状态。研究了外激励频率范围为0 ~ 100 Hz时，不同悬浮间隙下的谐振频率。随着悬浮间隙的不同，共振频率也不同。悬浮间隙与共振频率之间几乎呈线性关系。
The vertical vibration characteristics of a high-temperature superconducting maglev vehicle system are investigated experimentally. The displacement variations of the maglev vehicle system are measured with different external excitation frequency, in the case of a certain levitation gap. When the external vibration frequency is low, the amplitude variations of the response curve are small. With the increase of the vibration frequency, chaos status can be found. The resonance frequencies with difference levitation gap are also investigated, while the external excitation frequency range is 0–100 Hz. Along with the different levitation gap, resonance frequency is also different. There almost is a linear relationship between the levitation gap and the resonance frequency.
