中文摘要：

针对超导-永磁悬浮系统,分别采用描述超导宏观电磁场本构关系的磁通流动模型和磁通流动与蠕动模型,定量模拟了自由悬浮于超导体上方永磁体的振动。通过比较研究说明磁通蠕动效应对超导悬浮动力运动的影响程度以及这一影响随超导临界电流密度、系统外加激励振幅和频率的变化规律。

英文摘要：

　Based on macro-electromagnetic constitutive relation of superconductivity： flux flow model and flux flow and creep model,numerical simulation of vibration of magnet levitated above a superconductor in superconductor-magnet levitation systems has been carried out.By comparatively studying,the influences of flux creep in superconductor on dynamic behavior are exhibited,furthermore,the variation of these influences with the critical current density,the amplitude,and frequency of applied excitation have been investigated.
