摘　　要：高速磁浮交通车轨无接触运行,摆脱了轮轨黏着和弓网受流的约束,安全舒适、可靠性高、环境适应性强,具有不可替代的优势。文章基于高速磁浮交通系统的悬浮、导向和驱动三大核心技术,对常导电磁吸力型、低温超导电动斥力型、永磁电动斥力型和高温超导永磁钉扎型不同制式的高速磁浮交通系统特征与性能进行系统梳理,分析不同制式高速磁浮交通系统的技术难点、应用制约和适应性。结合建设交通强国的总目标及中国磁浮交通技术的研究与发展状况,提出常导电磁吸力型高速磁浮交通系统是目前中国突破轮轨交通运行速度制约的最佳选择。High-speed maglev trains are contactless with the track during operation,getting rid of the constraints of wheel-rail adhesion and current collection of pantograph and catenary.Therefore,they are safe,comfortable,highly reliable,and environmentally adaptable and have irreplaceable advantages.Based on the three core technologies of suspension,guidance,and driving of highspeed maglev transportation systems,this paper systematically summarizes the characteristics and properties of different types of high-speed maglev transportation systems,such as normal-conducting electromagnetic suction,low temperature superconducting electrodynamic repulsion,permanent magnetic electrodynamic repulsion,and high temperature superconducting permanent magnetic nailing.In addition,it analyzes the technical difficulties,application constraints,and adaptability of different types of highspeed maglev transportation systems.Combined with the general goal of building China into a strong transport country and the research and development of China’s maglev transportation technology,it is concluded that the high-speed maglev transportation system with normal-conducting electromagnetic suction is the best choice for China to break through the operating speed constraints of wheeled transport.
