Dynamic Performance of Low- and Medium-Speed Maglev Train Running on the Turnout

This study aimed to analyze dynamic performance of the low-and medium-speed maglev train on the turnout, by conducting a series of field tests on the Fenghuang maglev sightseeing express line.This study systematically analyzed and evaluated dynamic responses of vehicle body, suspension bogie, short rail joint, motor-driven long-span girder (LSG) and continuous beam of the turnout at different speeds and loads in time and frequency domains.Test results obtained in this study indicated that: 1) speed and load of the maglev train affected acceleration amplitude of the train and turnout; 2) vertical sperling indexes of the test train were less than 2.5, indicating that the train had good ride quality; and 3) resonance phenomenon of track occurred at 40 km/h.The findings of this study may serve as references for model validation and optimized design of low-and mediumspeed maglev train.
