    摘要: As a seismic wave travels along the separate supports of an extended structure, the structure is subjected to multiple-support excitation due to spatially varying ground motion and seismic wave propagation. Considering the seismic wave passage effect, this paper describes seismic analysis of a maglev vehicle moving on a multiply supported gudieway. The guideway system is modeled as a series of simple beams and the vehicle as a four degrees-of-freedom (DOFs) rigid bar equipped with multiple onboard PI+LQR hybrid controllers. The controller is used to regulate control voltage for tuning both magnetic forces of uplift levitation and lateral guidance in the maglev system. Numerical studies show that as a maglev vehicle is equipped with more supported magnets then they can provide more control gains for tuning the guidance forces of the moving vehicle. This conclusion is benefit and available to mitigate seismic-induced lateral vibration of a maglev vehicle running a guideway.
