Abstract Research purposes: At present, the medium and low speed maglev lines in China and abroad are relatively short, and the research on maglev fastening system focuses on the scheme and structural design, and lacks corresponding parameter research, type selection analysis, test methods, etc. Combined with the force and structural characteristics of medium and low speed maglev track, the main performance and parameters of fastening system are studied, the use of fastening system on maglev lines is analyzed and sorted. According to the relevant standards of railway fasteners, the assembly test method is proposed. The problems to be solved in engineering application are put forward, which provides suggestions for the development of medium and low speed maglev fastening system.
Research conclusions: (1) The fastening system for medium and low speed maglev track should have sufficient anti-creeping resistance, good three-dimensional adjustment capability, reasonable stiffness, convenient maintenance, etc. (2) The selection of fastening system should be comprehensively considered according to the line engineering conditions, in combination with distance adjustment capacity, fastener type and reliability, maintenance and repair, etc. (3) With reference to the railway rail fastening system, the assembly performance experiment of maglev fasteners are carried out. After 3 million fatigue tests, the components are not damaged, and all the indicators meet the requirements. (4) According to the characteristics of the maglev system, it is necessary to further study the multiple technical problems existing in the fastening system to improve its service performance. (5) The research results can provide reference for the research and design of fastening system for medium and low speed maglev track.

Key words： medium and low speed maglev fastening system type selection assembly experiment
