| Summary: | In order to improve the operational safety and save maintenance costs of rolling stock, this paper focused on the fatigue remaining life of rolling bearings for rolling stock, further investigated their service life rules, and identified the basic types of bearing service lives, namely fatigue life, precision life, and abnormal damage resistance life. Through statistics and analysis on the accuracy and probability of abnormal damage on rolling stock bearings before and after service operations, it established the relationships of bearing accuracy and abnormal damage survival rates associated with mileage, resulting in a mathematical model. Additionally, based on analysis on the variation laws of precision life and abnormal damage resistance life, it summarized total capacities of bearings applied in batches in different service life stages. This paper underscores the available value in the remaining life of bearings when applied in batch, and proposes suggestions for reasonable management of bearing service life. |
