The invention discloses an urban rail vehicle running gear bearing state maintenance method and system, and the method comprises the following steps: obtaining each original working condition state data of each part bearing of a vehicle running gear; processing the original working condition state data to obtain working condition states and bearing working condition state grades corresponding to the working condition states; imparting influence weights to the working condition states according to working condition types; giving degradation degree weights to the bearing working condition state grades corresponding to the working condition states; obtaining the health state grade of the bearing according to the influence weight and the deterioration degree weight; and maintaining the bearing according to the health state grade of the bearing. The maintenance method is clear in logic, safe, effective, reliable and easy and convenient to operate, accurate recognition can be conducted at the initial stage of bearing part faults, and vehicle maintenance is guided according to the health state of the bearing.

    本发明公开了一种城轨车辆走行部轴承状态维修方法及系统,方法包括如下步骤:一种城轨车辆走行部轴承状态维修方法,包括如下步骤:获取车辆走行部各部位轴承的各原始工况状态数据;处理所述各原始工况状态数据,以获取各工况状态以及各工况状态对应的轴承工况状态等级;分别对所述各工况状态按工况类型赋予影响权重;分别对所述各工况状态对应的轴承工况状态等级赋予劣化程度权重;根据所述影响权重和所述劣化程度权重获取轴承的健康状态等级;根据轴承的所述健康状态等级,对轴承进行维修。该维修方法逻辑清晰,安全、有效、可靠且操作简便,可以在轴承部件发生故障初期进行精准识别,并根据轴承的健康状态指导车辆维修。
