In vehicle dynamics research, a dynamics model is essential, as it provides the basis for the demonstration of early system design of vehicle as well as the verification and optimization of the dynamics performance of the final product. To promote the development of a permanent magnet (PM) Electrodynamic Suspension (EDS) in a maglev train, research was carried out in order to explore a fast dynamics modeling, with suspension system based on two-sided PM. First of all, a halbach array was taken as the object of study, with the analytical solution of its magnetic force obtained by theoretical derivation according to magnet filed and 2D analytical method; then, the magnetic force was discretized into a data matrix of displacement, force, and speed; thirdly, the data matrix was introduced in SIMPACK to establish a magnet-track relationship in scalar form, and a dynamics model of the two-sided PM EDS maglev system was finished by the theory of multi-body dynamics modeling; finally, the proposed modeling was validated by the agreement between theoretical derivation and dynamics model calculation of the heaving frequency and pitching frequency of the frame; at the same time, it was also validated by the agreement of dynamic responses between the modeling by vehicle-track coupled dynamics theory and the dynamic model calculation of the levitation gap and force. According to the established dynamics model, dynamic response of the system at the speed of 600 km/h was calculated, and the feasibility of the two-sided PM EDS maglev train was verified. The simulation speed of model which was established before is 50 times that of the mathematical model by the vehicle-track coupled dynamics, thus providing reference for the future research in this regard.
