Abstract

The high-speed rotating superconducting rotor can be made into a high-precision inertial device. Centrifugal deformation is one of the key factors affecting the drift speed of the rotating superconducting rotor's polar axis. The larger the drift speed, the worse the accuracy of the inertial device. Applying magnetic torque to the superconducting rotor to compensate for the magnetic disturbance torque generated by centrifugal deformation is one of the effective methods to improve the measurement accuracy of the inertial device made of a superconducting rotor. To compensate for the magnetic disturbance torque caused by centrifugal deformation accurately, we studied the centrifugal deformation effect of the rotating superconducting rotor. In this paper, the centrifugal deformation of the superconducting rotor is analyzed first. And then the influence of centrifugal deformation of the superconducting rotor on magnetic force was studied by Finite Element Method (FEM). The results show that centrifugal deformation can reduce the magnetic levitation force of the superconducting rotor, leading to suspension position drift. Finally, the drift speed of the superconducting rotor's polar axis caused by centrifugal deformation is investigated, including the drift speed caused by centrifugal deformation of the rotating superconducting rotor, as well as the drift speed generated by the coupling of centrifugal deformation and suspension position drift of the superconducting rotor. The research results provide a reference for more accurate compensation of magnetic disturbance torque caused by centrifugal deformation and further improve the accuracy of superconducting rotor inertial devices.

磁悬浮超导转子的离心变形效应研究

高速旋转的超导转子可制成高精度惯性装置。离心变形是影响旋转超导转子极轴漂移速度的关键因素之一。漂移速度越大，惯性装置的精度就越低。向超导转子施加磁力矩以补偿离心变形产生的磁干扰力矩，是提高超导转子惯性装置测量精度的有效方法之一。为了准确补偿离心变形产生的磁干扰力矩，我们研究了旋转超导转子的离心变形效应。本文首先分析了超导转子的离心变形。然后用有限元法（FEM）研究了超导转子离心变形对磁力的影响。结果表明，离心变形会降低超导转子的磁悬浮力，导致悬浮位置漂移。最后，研究了离心变形引起的超导转子极轴漂移速度，包括旋转超导转子离心变形引起的漂移速度，以及超导转子离心变形和悬浮位置漂移耦合产生的漂移速度。研究成果为更精确地补偿离心变形引起的磁干扰力矩提供了参考，并进一步提高了超导转子惯性装置的精度。

期刊介绍： Physica C (Superconductivity and its Applications) publishes peer-reviewed papers on novel developments in the field of superconductivity. Topics include discovery of new superconducting materials and elucidation of their mechanisms, physics of vortex matter, enhancement of critical properties of superconductors, identification of novel properties and processing methods that improve their performance and promote new routes to applications of superconductivity. The main goal of the journal is to publish: 1. Papers that substantially increase the understanding of the fundamental aspects and mechanisms of superconductivity and vortex matter through theoretical and experimental methods. 2. Papers that report on novel physical properties and processing of materials that substantially enhance their critical performance. 3. Papers that promote new or improved routes to applications of superconductivity and/or superconducting materials, and proof-of-concept novel proto-type superconducting devices. The editors of the journal will select papers that are well written and based on thorough research that provide truly novel insights.
