Summary:

A noticeable noise and vibration occurred when the Mass Rapid Train turned on a rail with a large turning angle. A study was performed to investigate the source of the noise and vibration, to find the root causes, and to discuss the corrective actions to improve the issue.The investigation indicates the noise occurs between the slewing ring bearing and the friction sets. The slewing ring bearing is located between the body and chassis systems. It provides a relative rotation between the body and chassis. The friction sets provide friction forces to prevent abrupt movements and to help to stabilize the relative motions between the body and chassis systems.The study shows under certain contact conditions unsmooth turning would occur and cause the noise and vibration. A corrective action was suggested to improve the condition
