| Abstract | This paper presented a computational framework of interaction analysis for an EDS (electrodynamic suspension) maglev train traveling over a suspension bridge shaken by horizontal earthquakes. The suspended guideway girder is modeled as a single-span suspended beam and the maglev train traveling over it as a series of maglev masses. To tune the magnetic forces in a maglev suspension system, an on-board hybrid LQR+PID controller is designed to control the dynamic response of a running maglev mass. Then the governing equations of motion for the suspended beam associated with all the controlled maglev masses are transformed into a set of generalized equations by Galerkin’s method, and solved using an incremental-iterative procedure. Numerical investigations demonstrate that when a controlled maglev train travels over a suspended guideway shaken by horizontal earthquakes, the proposed hybrid controller has ability to reduce the vehicle’s acceleration response for ride quality. Key-Words: maglev system; earthquake; iterative-incremental method; suspended guideway. |
