  • 超导转子磁悬浮装置可制作角速度传感器, 超导转子的高速驱动是实现超导转子磁悬浮装置高精度的基础. 超导转子的热损耗和径向质量偏心会使超导转子在驱动过程中热失超和共振, 所以在超导转子的驱动过程中, 超导球腔中需要保持定量的氦气, 以此传递超导转子的产热和抑制超导转子的共振. 但氦气同时会对超导转子产生阻力, 影响超导转子的驱动过程. 基于此开展了超导转子在氦气中的阻力矩研究, 首先引入范德瓦耳斯方程分析了低温氦气的性质, 提出了一种低温氦气对超导转子阻力矩的研究方法, 并进行实验验证. 然后基于有限元方法分析了超导转子旋转驱动的电磁结构和电磁力矩, 并研究了氦气对超导转子加速过程的影响, 包括临界驱动速度、超导转子的加速时间和氦气对超导转子的摩擦热等. 研究结果提供了一种低温气体对旋转超导体阻力矩的研究方法, 为进一步优化超导转子的驱动过程提供参考.
    The superconducting rotor magnetic levitation device can be used to make an angular velocity sensor, and the high-speed rotating superconducting rotor is the basis for achieving high-precision measurement of the superconducting rotor magnetic levitation device. The heat loss and radial mass eccentricity of the superconducting rotor can cause thermal quenching and resonance in the driving process, which is unfavorable to the driving process of the superconducting rotor. Therefore, it is necessary to maintain a certain quantity of helium gas in the superconducting cavity in the driving process, to transfer the heat generated by the driving process and avoid its resonance. But helium gas also has a drag torque on the rotating superconducting rotor, affecting the driving process of the superconducting rotor. Based on this, the drag torque of the helium on the rotating superconducting rotor is studied. Firstly, the Van der Waals equation is introduced to analyze the properties of low-temperature helium, and a method of studying the drag effect of low-temperature helium on the rotating superconducting rotor is proposed based on Reynolds law and Stoke’s first problem. Then, an experiment on superconducting rotor speed attenuation is conducted to verify the proposed analysis method. Based on the finite element method, the driving electromagnetic structure and driving torque of the superconducting rotor are analyzed. Finally, the influence of helium on the driving process of the superconducting rotor is investigated, including critical driving speed, acceleration time of the superconducting rotor, and frictional heat of the helium on the superconducting rotor. The research results further enrich the study of the drag torque of low-temperature gases on rotating superconductors, providing a reference for further optimizing the driving process of superconducting rotors.
