Curve Negotiation Characteristics of the Side-Suspended High-Temperature Superconducting Maglev System

Thanks to its superb curve negotiation characteristics, the side-suspended high-temperature superconducting (SS-HTS) maglev system boasts a great potential for high-speed transportation.The SS-HTS maglev system, however, significantly differs in suspension features from the conventional maglev system because of its unique side-suspended structure.To improve suspension performance, the field-cooling technique of superconducting bulks in the SS-HTS system was investigated through a number of experiments.To fit the experimental data, the authors proposed the mathematical models of the levitation and guidance forces as well as the optimal field-cooling position.Furthermore, a dynamic model was developed for the SS-HTS maglev vehicle operating on a curve line, and the curve negotiation characteristics were simulated for the maglev vehicle.Finally, the stability of the curve negotiation for the SS-HTS system was assessed using the Sperling index.The results show that the SS-HTS maglev vehicle can pass over bends at a certain speed.The authors also recommended the suspension parameters the maglev vehicle.
