针对YBCO块材和NdFeB永磁体构成的高温超导磁悬浮系统,研究了永磁体在不同荷载时系统的动态响应特性.实验结果表明,当振动频率较低时,悬浮系统动态响应与外加激励信号一致,外加荷载的改变对系统响应基本无影响.随着频率的增加,外加荷载对系统的影响明显增强.荷载越大,系统的抗干扰能力越强.这对高温超导磁悬浮系统的应用有一定的指导意义.
For the high-temperature superconducting maglev system composed of YBCO bulk and NdFeB permanent magnet,dynamic response of it carrying different load was studied.The experimental results show that responses of maglev system are coincide to the external vibration signal at lower vibration frequency,and that changing the load on the permanent magnet did not vary response behave of the system.With the increasing of frequency,influence of the load significantly increased.The anti-interference of the system enhanced with the load increase.This may be helpful in the application of the high-temperature superconducting maglev system in the future.
