The development and application of guideway monitoring vehicle for super speed maglev

For high speed maglev using ElectroMagnetic Suspension(EMS) as levitation method, the gap between vehicle and guideway surface is maintained by only about 10mm. Therefore, to prevent the contact and improve the ride comfort, the guideway irregularity should be controlled below a certain level. Especially, the LSM stator pack attached under guideway should be clamped without any looseness, otherwise the serious collision would happen. In this study, to monitor the guideway status, an inspection vehicle is proposed and the monitoring algorithms are reviewed.
