Track beam is an important structural component in maglev transportation. The analysis of its structural performance is quite critical, especially for the coupled dynamic analysis under the action of high-speed moving train, which is directly related to the operation safety and stability of the train. The dynamic coupling of the 600 km/h ultra-high-speed maglev track beam was studied, the train model was based on 5 rigid bodies and 30 degrees of freedom system, and the spatial coupling analysis model of the maglev track beam was established by using the Timoshenko beam element model with shear effect considered. For the specific implementation of the coupling analysis in the cross platform framework, the multi-body dynamics software Simpack, the large-scale finite element software ANSYS and the visual simulation tool MATLAB/Simulink modeling method were used, and the PID controller was introduced to actively control the whole suspension control system. The whole coupling system was divided into the main vehic
