Simulation of the Braking Effects of Permanent Magnet Eddy Current Brake and Its Effects on Levitation Characteristics of HTS Maglev Vehicles

High-temperature superconducting (HTS) magnetic levitation (maglev) trains for designed high speed need a non-contact braking method that can produce stable and sufficient forces to ensure the safety of train during emergency braking. In order study effects permanent magnet eddy current (PMECB) used in HTS maglev vehicles its on performance vehicles, an equivalent two-dimensional simulation model PMECB test vehicle under different working air gaps 5 mm, 10 15 mm 20 was established Maxwell software. Then, 6 degree freedom dynamic Universal Mechanism simulation, normal force not considered, only detent taken as excitation vehicle. The results show PMECBs reduce relatively low few seconds. During operation PMECBs, height Dewar will be affected, maximum variations heights occur Dewars at both ends These help us understand action enrich design idea systems equipped with PMECBs.
