Vibration Analysis of the Bogie of Medium-speed Maglev Trains with Mid-mounted Linear Motor

Abstract

In this paper, the LMS Virtual. Lab Motion was used to analyze the dynamics of the bogie of Medium-speed maglev trains with a mid-mounted linear motor. Firstly, the multi-rigid-body model of the single bogie, the decentralized levitation control scheme and the magnet-rail relationship model were built in LMS Virtual. Lab Motion. The modal frequencies and modal shapes were obtained by using the linearization analysis function of the software. The modal analysis results were verified with the vibration response of the frequency sweeping analysis while applying a vertical force on the mid-mounted linear motor.
