High-speed maglev train-guideway–tunnel–soil modelling of ground vibration

Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit, 2011
A fully coupled three-dimensional multi-body finite element model coupled with a perfect matching layer approach is presented to study the ground vibrations created by a high-speed maglev train running in a tunnel. The maglev train is assumed to consist of multiple rigid bodies and the magnetic force between the maglev train and its guideway is ...

Fault Diagnosis of Relative Position Sensor for High Speed Maglev Train

2019 Chinese Automation Congress (CAC), 2019
The relative position sensor provides phase angle information for the traction system. The failure of the sensors directly affects whether the train can operate normally. Based on the analysis of the sensor, the common faults of the sensor are analyzed, and the corresponding fault features are extracted.
