“…Охлаждение сверхпроводника может осуществляться двумя способами: с помощью криокулера и жидким хладагентом (как правило, жидким азотом). В работе [15] были рассмотрены различные аспекты криокулерного охлаждения. В настоящей статье мы проводим сравнение эффективности криокулерного и азотного охлаждения стопок ВТСП лент как элементов транспортной магнитолевитационной системы в различных динамических условиях изменения магнитного поля.…”

Background: analysis of the influence of cooling conditions of high-temperature superconducting elements on the power characteristics of a maglev system under conditions of rapidly changing magnetic fields Aim: analysis of the influence of cooling conditions of high-temperature superconducting elements on the force characteristics of a magnetic-levitation transport platform under conditions of rapidly changing magnetic fields caused by the inhomogeneity of the magnetic track. Methods: numerical analysis of the maglev system was performed by the finite element method in the Comsol Multiphysics engineering simulation software. Results: at fast, more than 5 T/s, magnetic field change rates, due to the motion of the superconductor in a magnetic field with a non-uniform local distribution, the preferred method of cooling is the use of cryocooler technology. At rates of change of the magnetic field less than 5 T/s, it is permissible to use liquid nitrogen as a cooler. Conclusion: The developed numerical model makes it possible to predict the dynamic characteristics of levitation systems of various scales and can be applied to contactless transport, as well as in rotating machines, including kinetic energy storage devices.

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.
