A fully coupled three-dimensional multi-body finite element model coupled with a perfect matching layer approach is presented to study the ground vibrations created by a high-speed maglev train running in a tunnel. The maglev train is assumed to consist of multiple rigid bodies and the magnetic force between the maglev train and its guideway is simulated using linear springs and dampers. The guideway, tunnel and soil are modeled by three dimensional finite elements with PML as the artificial boundary condition. The results obtained for a maglev train running on a viaduct line show a reasonable agreement with available experimental data, which demonstrates the validity of the proposed model. This model is subsequently utilized to simulate the vibration levels created by the train running in a tunnel in terms of parameters related to the maglev train, tunnel, and soil.
