摘要：
In light of the risk of and reasons for the abnormal vibration, an analysis of this vibration is conducted. Signal processing methods such as FFT, conversion between different vibration data types, orbits of axis, waterfall map, and waterfall map with characteristic frequencies of bearing are used to reveals the features of abnormal vibration. Then, the details of the structure and the data of multi-test points are analyzed, and the type of vibration is determined to be resonance on the waterfall map. The modals of the vibration components computed with FEA(finite element analysis) and the bearing's characteristic frequencies with theoretical formulas lead to the conclusion that the bearing results in the abnormal vibration. Finally, detection results of bearing after disassembling are supplied to show that the methods and procedure of analysis are reasonable. The analysis of the abnormal vibration is referenced for vibration faults diagnosis. © 2019, Editorial Department of JVMD. All right reserved.
