轴承疲劳故障诊断方法的实验研究

Experimental studies of diagnostic methods for bearing fault

基于多组轴承实际运行状态的监测实验，对信号变化特征作了全面描述，弥补了依据模拟故障试验的不足．通过多方面的分析、比较，得出了一套用于滚动轴承疲劳故障在线监测和诊断的有效方法．

Based on series of experimental observation of the bearing in running, a minute description of the signal characteristics is given making up deficiency of simulative test bearing failure. An effective method is advanced after a comprehensive analysis and comparison, which allows to be used in online monitoring and fault diagnosis for roller bearings.
