Suspension influence analysis of track irregularity of maglev train

Irregularity of track is a primary factor that affects both safe-stabilization and ride comfort of maglev train. In this paper, suspension system model which takes irregularity of track into account is built based dynamics theory, and using Matlab tools, law of suspension state effected by irregularity of track is analyzed. The emulational results show that all kinds of track irregularity directly effect the suspension gap and current. In addition, this results also provide important groundwork for the next research about forecast maintenance of track.
