Study on the Damping Characteristics of Superconducting Electrodynamic Suspension Using a Field-Circuit-Motion Coupled Model

EDS， analytical model， FEM model， damping coefficient， analysis

The purpose of this paper is to study the vertical and lateral damping characteristics of the superconducting electrodynamic suspension (EDS) system. We used a field-circuit-motion coupled model to perform the analysis and a moving interval acceleration algorithm was implemented to speed up the calculation. Moreover, we also introduced a 3-D numerical model using finite element method (FEM). The validity of the analytic model was confirmed by the comparison of the measured and calculated data. Based on the model, we studied the influence of the train speed, vibration amplitude and vibration frequency on the vertical and lateral average damping coefficients. This work could be helpful for vibration control design of the EDS systems, such as vacuum tube high-speed flying train, superconducting maglev, space magnetic levitation electromagnetic launch and so on
