Aim: This study aims to analyze the influence of harmonic excitations during bearing misalignment on the power and mechanical characteristics of a high-speed magnetic bearing based on tape high-temperature superconducting composites.

Methods. Numerical multiphysics analysis of a superconducting magnetic bearing was performed using the finite element method in Comsol Multiphysics.

Results. When there is a deviation from coaxiality in the arrangement of the magnetic elements of the HTS bearing, harmonic excitations, vibrations, and beats appear, leading to a deterioration in the load characteristics of the device and a decrease in the dynamic permeability of the magnetic system.

Conclusion. The developed numerical model makes it possible to predict the dynamic and mechanical characteristics of high-speed HTS bearings and can be used to develop high-speed rotor systems.

Цель. Анализ влияния гармонических возбуждений при несоосности подшипника на силовые и механические характеристики высокооборотного магнитного подшипника на основе ленточных высокотемпературных сверхпроводящих композитов.

Методы. Численный мультифизический анализ сверхпроводящего радиально-упорного магнитного подшипника выполнен методом конечных элементов в среде инженерного моделирования Comsol Multiphysics.

Результаты. При отклонении от соосности в расположении магнитных элементов ВТСП подшипника проявляются гармонические возбуждения, вибрации и биения, приводящие к ухудшению нагрузочных характеристик устройства и снижению динамической проницаемости магнитной системы.

Заключение. Разработанная численная модель позволяет прогнозировать динамические и механические характеристики высокооборотных ВТСП подшипников может быть применена для разработки высокоскоростных роторных систем.
