Levitation and Guidance Characteristics of Superconducting Electrodynamic Maglev Train

Abstract:

Taking the superconducting electrodynamic maglev train as the research object， a field-circuit-motion coupling numerical model of a bogie and levitation/guidance coil was established. Then， the model was solved and its correctness was verified. Finally，the levitation force and guidance force of a bogie under different vertical displacements and lateral displacements were analyzed and the relationship between non-cross connection and cross-connection figure-eight-shaped coils was revealed based on the model. The results show that the force generated by no-cross connection figure-eight-shaped coils is mainly the levitation force， and the force generated by cross connection figure-eight-shaped coils is mainly the guidance force. With the increase of lateral displacement， the guidance-drag ratio increases first and then decreases. With the increase of vertical displacement， the levitation-drag ratio also increases first and then decreases.
