“…Так, контроль вертикальных вибраций динамической ВТСП системы, подверженной внешним возмущениям обсуждался и моделировался в работе [1]. Горизонтальные колебания сверхпроводника над кольцевым постоянным магнитом исследовались в работе [2]. Представленная в работе [2] система также предполагает использование ВТСП для космического применения в качестве регулятора вибрационной стойкости.…”

“…Горизонтальные колебания сверхпроводника над кольцевым постоянным магнитом исследовались в работе [2]. Представленная в работе [2] система также предполагает использование ВТСП для космического применения в качестве регулятора вибрационной стойкости. Разработки высокоскоростных транспортных систем на основе явления магнитной левитации, в том числе на основе ВТСП, начали получать широкое распространение более 30 лет назад [3][4][5][6].…”

МОДЕЛИРОВАНИЕ ДИНАМИЧЕСКИХ ХАРАКТЕРИСТИК МАГНИТОЛЕВИТАЦИОННОЙ ТРАНСПОРТНОЙ ПЛАТФОРМЫ В ПРОЦЕССЕ ДВИЖЕНИЯ, РАЗГОНА И ТОРМОЖЕНИЯ 1Цель: моделирование динамических характеристик магнито-левитационной платформы на основе высокотемпературного сверхпроводника в процессе движения, разгона и торможения.Методы: численный анализ магнитной левитационной системы выполнен методом конечных элементов в среде инженерного моделирования Comsol Multiphysics.Результаты: при прямолинейном движении поперечные колебания не превышают 15 %, а увеличение скорости и массы подвеса не оказывает существенного влияния на амплитуду вибраций. В случае вертикальных колебаний увеличение массы и скорости платформы приводит к увеличению вибрационной стойкости системы.

Background: When developing high-speed transport systems based on the magnetic levitation phenomenon, it is necessary to take into account a huge number of factors that affect the characteristics and stability of this type systems. One of the simplest and most convenient methods for achieving these goals is numerical simulation. Aim: simulation of the dynamic characteristics of a magnetic suspension based on a high-temperature superconductor during movement, acceleration and deceleration. Methods: numerical analysis of the magnetic levitation system was performed by the finite element method in the Comsol Multiphysics engineering simulation software. Results: during straight motion, lateral vibrations do not exceed 15 %, and the suspension speed and mass increase does not have a significant effect on the vibrations amplitude. In the case of vertical oscillations, the platform mass and speed increase leads to an increase in the vibration resistance of the system. With an increase in the turning radius of the track, the maximum possible speed of entering the turn without detaching the suspension from the magnetic track increases non-linearly. Conclusion: The developed numerical model makes it possible to predict the dynamic characteristics of levitation transport and can be applied to systems of various scales.

“…Its intrinsic stability [9,10] is an important advantage over active magnetic levitation, which is inherently unstable as introduced by Earnshaw's theorem [11] and typically require more complex control strategies, higher power consumptions and have reduced reliability [12,13]. Due to this list of advantages, superconducting devices has made possible to build flywheels for energy storage [14][15][16], superconducting magnetic bearings [17,18], vibration isolators for space structures [19] and precise positioning devices [20].…”

In this paper, the dynamic behavior of a one degree-of-freedom (DOF) contactless linear slider based on superconducting magnetic levitation is experimentally analyzed. The device is intended for precision positioning of an optic mirror in cryogenic environments. Different prototypes of this device have been tested at cryogenic temperatures (77 K), and their mechanical behavior characterized in the sliding direction for forced and unforced oscillations. Experimental results reveal that the slider is self-stable at the initial equilibrium position and the dynamic behavior fits well an underdamped harmonic oscillator. Finally, the device showed great potential for horizontal vibration isolation, acting as a low-pass filter with a resonance at about 0.9 Hz.
