| Abstract: | Aiming at the widespread phenomenon of running gear＇s periodic abnormal noise during the normal operation for XI＇an metro line 2, this paper carries out the on-site investigation and data analysis, and confirms that the root cause is mainly due to the interface problems between the vehicle traction system and the air braking system, which leads wheel abrasions and rolling circle overrun. Several schemes which can fundamentally fix up the abnormal sound has been proposed based on the actual situation. |
