The exploration of high-speed (600 km/h) maglev transportation technology in China is stepping forward the deep-water zone, and developing the whole process top-down design systems including matching design of maglev train and line dynamics parameters is thus imperative. Firstly, this paper elucidates the dynamic behavior features of the high-speed electromagnetic suspension (EMS)-type maglev train and the regulation and control requirements. Then, the paper reviews research progress on the dynamics design of the high-speed maglev train, overhead girder, and line in the past 20 years and point out the existing problems. Thirdly, the paper discusses the technological challenges of the multi-field coupling dynamic simulation of maglev transportation, comprehensive suppression of levitation/guidance airgap fluctuation, comprehensive vibration attenuation of maglev train, and matching design of train and line dynamics parameters. Finally, it is advocated that the research on cross-disciplinary integration of maglev transportation should be promoted by the organized scientific research paradigms. In addition, it is necessary to establish matching design theories and technologies of train and line dynamics parameters oriented toward stable and comfortable train running, so as to support the research and development of high-speed (600 km/h) maglev transportation engineering technology and the construction of test lines.
