Abstract

A maglev train-guideway-tunnel-soil coupling system model is developed to study the wave propagation problem caused by high speed electromagnetic suspension (EMS) maglev train travelling through tunnel. The maglev train is simulated by multi-bodies, which takes the rigid body characteristics of the body-bogie-magnet system into account. The guideway-tunnel-soil system is simulated by 3D finite elements, and the unbounded domain is simulated by Perfect match layer (PML). The interaction between maglev train and guideway is simulated by the equivalent spring/damping magnetic force model. The dynamic factor of guideway is well estimated comparing with the German design guideline. A certain parameters related to the maglev train, tunnel and soil are considered to investigate the vibration of tunnel and ground surface.

 

Key words: Maglev train, finite element, perfect match layer (PML), tunnel, wave propagation.
