摘　　要：采用数值模拟和实验2个方面研究了高温超导磁悬浮系统在不同的场冷却高度和负载下,温度对系统横向动力学特性的影响,实验结果与理论结果吻合较好.结果表明,降低场冷却高度或温度会增加系统的动态刚度和共振频率,而增加负载则会显著降低系统的共振频率和稳定性.为确保系统安全运行必须保证适度的工作间隙,并适当降低工作温度以提高系统稳定性和承载能力.In this paper,the effect of temperature on the lateral dynamic properties of a high-temperature superconductor-permanent magnet(HTS-PM) system is investigated by both numerical simulation and experiments at different field cooling heights(FCH) and loads.The experimental results are in good agreement with the theoretical results.The results show that decreasing the FCH or temperature increases the magnetic stiffness and resonance frequency,while increasing the load significantly decreases the resonance frequency and stability of the system.Considering the moderate working gap that must be guaranteed to ensure safe operation,moderately lowering the working temperature should be the best choice to improve the stability and load-carrying capacity of the system.
