The invention provides a train running gear wheel health management method and system. The method comprises the steps that vibration data, impact data, fault diagnosis data, wheel set state data and wheel set production overhaul data are acquired; preprocessing the vibration data, the impact data, the fault diagnosis data, the wheel set state data and the wheel set production maintenance data to obtain first processing data; according to the first processing data, whole vehicle out-of-round fault analysis, whole vehicle wheel set size overrun analysis and whole vehicle non-out-of-round fault analysis are carried out, and a first fault level, a second fault level and a third fault level are obtained respectively; calculating a fault type index according to the first fault level, the second fault level and the third fault level; and obtaining residual life prediction data of the train wheels, and performing maintenance decision analysis according to the fault type index and the residual life prediction data to obtain a maintenance guidance suggestion. According to the invention, health state evaluation and maintenance guidance can be accurately and effectively carried out on the wheels of the running gear of the train.
