To explore the dynamic characteristics of the new type of maglev train, a new model with 56 degrees of freedom was established and simulated, and a single suspension frame model was used as a test rig for ride comfort. The simulation results show that the new type of maglev train can be stable operation at the speed of 140km/h on the straight line; Lateral acceleration of car body is less than 0.2 m/s2; vertical acceleration of car body is less than 0.5m/s2; the new type of maglev train can stably pass through the curve with the radius of 50m at the speed of 30km/h; the largest car body roll Angle is less than 0.04 rad; lateral acceleration of car body is less than 1m/s2; vertical acceleration of car body is less than 0.1m/s2; dynamic variation of levitation clearance is only 0.5mm. The test results show that car body vertical acceleration related to ride comfort is about 0.5m/s2 at the speed of 140km/h.
