| 摘 要： | 基于Bean临界态模型,针对目前的高温超导磁悬浮车系统,提出了一种模拟计算方法,该方法可计算在时变外磁场中块材导向力的衰减变化情况。通过对时变外磁场中块材温度、俘获磁通以及导向力等参数变化情况的实验结果和计算结果的对比,证实了该模拟计算方法的有效性。该模拟计算方法可用于定性研究高温超导块材的导向力性能在时变外磁场作用下的变化情况,为高温超导磁悬浮车的研究和工程实践提供了较为重要的科学依据。

| Abstract: | Based on the Bean critical model, a simulation method was adopted to calculate the guidance force decay of the bulk exposed to the time-vary magnetic field for the current HTS maglev system. Compared the experimental results with the simulation ones, it was found that the simulation method is feasibility and can qualitatively reveal the characteristics of guidance force of HTS bulk in this situation and provide important scientific bases for the research and engineering practice of HTS Maglev vehicle. |
