Stability Simulation and Analysis of Maglev Vehicle at Different Speed Based on UM

High-speed maglev train is an excellent mode of transportation to build a transportation network because of its high safety, low emission, low energy consumption, low noise and strong climbing ability.The safety, stability and comfort of high-speed maglev train are closely related to the running speed and the random track irregularity, so it is necessary to study the corresponding relationship between the running speed, the random track irregularity and the stability.In order to ensure the safety and stability of high-speed maglev train in highspeed running, a dynamic model of high-speed maglev vehicle is established by UM based on Shanghai TR08 maglev train to carry out simulation analysis of its response to various track irregularity stimulations at different speeds and study the change law of stability of maglev train at different speeds, so as to provide a useful reference for the design optimization of high-speed maglev vehicle and the irregularity control of maglev line.
