Research on Numerical Method for High-Speed Maglev Vehicle-Bridge-Foundation Coupling

The finite element software and multi-body dynamics software are used to establish the analysis model of ground vibration caused by TR08 high-speed maglev vehicle. The maglev vehicle and viaduct are built in the rigid dynamics software. The three-dimensional hexahedron finite element is used in the soil calculation domain to calculate the domain boundary. The impedance and scattering properties are modeled by a three-dimensional viscoelastic dynamic artificial boundary. It is assumed that the TR08 high-speed maglev trains of one vehicle group are operated in straight line at different speeds, and the ground vibration characteristics generated by the numerical method are simulated and analyzed. Compared with the existing research results, the calculation results of the method are basically consistent with the test results, and the ground vibration caused by the wheel-rail train is much larger than that of the maglev train under the condition of the same speed and other conditions.
