Abstract
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.
