TheEMS (Electromagnetic Suspension) high-speed maglev train employs electromagnetic force as the primary means for both levitation and guidance The safety and comfort when the train transitions from a straight line to a small radius curve need in-depth research. Taking a small radius curve of 400 m as an example, this paper first theoretically calculates the curve and transition curve lengths, cross slope angles, and the safe passing speed of the train. Considering the intricate active suspension and guidance control system, a precise dynamic model of the EMS high-speed maglev train is constructed, calibrated with theoretical line condition parameters for enhanced academic rigor. The kinematic posture and vibrational responses of the car-body, secondary suspension, suspension frame, and associated components are comprehensively simulated and analyzed, with a critical evaluation of the train’s curve traversal performance. The results show that, according to the theoretical calculation of R 400 m small radius curve parameters, when the train passes at the speed of $88.64 \mathrm{~km} / \mathrm{h}$, the roll angels of the car-body and suspension frame are within the safe range, the fluctuation of levitation gap is not exceed 4 $\mathbf{m m}$, and the fluctuation of guidance gap is close to $\mathbf{6} \mathbf{~ m m}$.
