【Abstract】 The basic princples of vibration test and fault diagnosis and the application in drive system of cement grinding mill were introduced. On the base of introducing vibration test method, system composition, layout of measuring point and the count of fault characteristic frequency, etc, combined with the test results, the fault diagnosis of drive system of cement grinding mill were made by integrated application of amplitude domain analysis, time-domain analysis and frequency-domain analysis. The diagnosis is consistent with the practical situation.更多还原
