Review and Prospect of R&D of High-speed EMS Guideway Structures
The guideway structure is the most important infrastructure of the high-speed elec-tromagnetic levitation transportation system,which is also the main control factor of the system construction cost.The system characteristics of guideway structure are analyzed.Combined with the development history after the introduction of guideway structure technology in China,the R&D achievements in the past 20 years are summarized into five phases:original test phase in German,construction of Shanghai line,R&D for medium and long-distance line application,development of maintenance and evaluation technology and R&D for higher speed,etc.The various solutions and engineering practical experience are systematically described and the future research direction is proposed,which can provide important support for the development of China's 600 km/h high-speed electromagnetic levitation transportation system.
