滚动轴承故障诊断实验研究

Experimental Study on the Fault Diagnosis of Rolling Bearing

摘要: 本文介绍了滚动轴承的常见故障，包括滚动轴承外圈故障、内圈故障和滚动体故障，并对滚动轴承故障进行实验研究。利用故障模拟实验台获得了正常信号和故障信号，通过经验公式求得不同故障的频率；采用时域方法和频域方法对故障进行分析，发现时域分析方法和频域分析方法有各自的优点，故障诊断结果与实际故障相符，表明该实验台可以较好地模拟滚动轴承的故障。

Abstract: This paper introduces the common faults of rolling bearing, including outer ring, inner ring of the rolling bearing and rolling element, and carries out experimental research on the faults of rolling bearings. It obtains the normal signal and fault signal by using fault simulation experiment table and gets the frequencies of different faults according to relevant empirical formulas. It is found that time domain analysis and frequency-domain analysis method have their own advantages through the analysis of fault by means of time domain and frequency domain method and the fault diagnosis results are in consistent with the actual faults, indicating that experiment table can well simulate the fault of rolling bearing.
