摘要：
The maglev transportation system has received extensive attention and research with its characteristics of wide speed domain, low noise, environmental protection and energy saving, non-contact suspension and guidance. In the dynamics of the maglev train-bridge coupling systems, maglev force, the interaction force between the bridge and the maglev train, is the most fundamental excitation source for the vibration of the maglev train-bridge coupling system. It is extremely important to calculate and analyze the force in an accurate way. Through literature analysis and refinement, the levitation characteristics and the basic principles of the electromagnetic suspension, the electrodynamic suspension, and the high-temperature superconducting suspension were described briefly. A summary was given on the formulas of the maglev forces under the three levitation modes and an analysis was conducted on their respective advantages, disadvantages and applicable situations. The research result can provide certain reference values for the determination of the maglev forces in the maglev train-bridge coupling system under different maglev systems. © 2023 Science Press.
