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.
Aiming at the high temperature superconducting magnetic suspension system composed of YBCO block and NdFeB permanent magnet, the dynamic response characteristics of the permanent magnet under different loads are studied.The experimental results show that when the vibration frequency is low, the dynamic response of the suspension system agrees with the applied excitation signal , The change of applied load has little effect on the system response.With the increase of frequency, the impact of applied load on the system is obviously enhanced.The larger the load, the stronger the anti-interference ability of the system.This application of high temperature superconducting magnetic suspension system is certain The guiding significance.
