摘要

为提高铁路机车车辆的运行安全性和节约维修成本，文章在铁路机车车辆滚动轴承疲劳剩余寿命研究基础上，继续研究铁路机车车辆滚动轴承运用寿命规律，提出轴承运用寿命的基本类型包括疲劳寿命、精度寿命与抗异常损伤寿命；对铁路机车车辆轴承运用前、运用后的精度及异常损伤概率进行统计与分析，给出了轴承精度、异常损伤存活率与里程的关系，提炼出数学模型，分析精度寿命与抗异常损伤寿命变化规律，给出轴承批量各运用寿命阶段工作总量。指出轴承批量运用剩余寿命的可利用价值，提出合理管理轴承运用寿命的建议。

Abstract

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.
