摘　　要：中国600 km/h速度级高速磁浮交通技术探索逐渐进入“深水区”,构建包括磁浮车线动力学参数匹配设计的全过程正向设计体系势在必行。文章阐述了高速常导磁浮列车的动态行为特征及调控要求,回顾总结了21世纪以来高速磁浮列车、轨道梁和线路动力学设计研究进展和存在的问题,分析了磁浮交通多场耦合动力学仿真、悬浮导向气隙波动综合抑制、磁浮列车综合减振、车线动力学匹配设计面临的技术挑战,建议以有组织科研范式变革推进磁浮交通多学科交叉融合研究,创建面向行车稳定舒适的车线动力学参数匹配设计理论与技术,为600 km/h速度级高速磁浮交通工程技术研发及试验线建设提供支撑。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.
