货车轴承段修在线故障诊断

On-Line Failure Diagnosis for Freight Train Bearings at Stage Repair

通过对多套典型状态货车轴承的试验 ,提出在幅值域用无量纲振幅参数的方法对货车滚动轴承进行段修在线故障检测 ,是一种比较简单易行的检测手段 ,可供段修使用。附图 6幅 ,表 2个 ,参考文献 5篇。

Through tests of several typical freight train bearings, a bearing failure diagnosis method by adopting dimensionless vibration amplitude parameter within amplitude domain is developed. It is a simple and feasible checking approach, and can be used in stage repair
