主　　题：Medium–low-speed maglev Vehicle–turnout coupled system Field test Vibration characteristics Ride quality 

摘      要：The steel turnout is one of the key components in the medium–low-speed maglev line ***,the vehicle under active control is prone to vehicle–turnout coupled vibration,and thus,it is necessary to identify the vibration characteristics of this coupled system through field *** this end,dynamic performance tests were conducted on a vehicle–turnout coupled system in a medium–low-speed maglev test ***,the dynamic response data of the coupled system under various operating conditions were ***,the natural vibration characteristics of the turnout were analysed using the free attenuation method and the finite element method,indicating a good agreement between the simulation results and the measured results;the acceleration response characteristics of the coupled system were analysed in detail,and the ride quality of the vehicle was assessed by Sperling ***,the frequency distribution characteristics of the coupled system were *** these test results could provide references for model validation and optimized design of medium–low-speed maglev transport systems.
