Experimental research on characteristics of early stages rub-impact rotor transient speed fluctuation

SUN Yun-ling1,HE Bao-shan2,JIANG Xue-wu1(1.College of Power Engineering,Naval Univ.of Engineering,Wuhan 430033,China; 2.Unit No.92957,Dinghai 316000,China)  
The rotor transient speed fluctuation signal contains so much rub-impact information which is hardly influenced by faults such as imbalance,so it can be used to diagnose early-stage rub-impact faults between the rotor and the stator.The rotor transient speed fluctuation rules were studied in simulation and experimentation.Firstly,the simulation model of rub-impact is established for speed fluctuation.Secondly,the model was used to find solution under the first order sympathetic rotating speed.It is found that the phenomena of one-point rub-impact,local rub-impact happen in turn with an increase in speed and the rotor transient speed fluctuation amplitude rises in turn.The main component in frequency spectrum is the rotating frequency in one-point rub-impact or local rub-impact.But the amplitude of high order multiple frequency with one-point rub-impact is stronger than that with local rub-impact.Finally,experiments on normal status,one-point rub-impact and two different degrees of local rub-impact were carried out respectively.The results reveal that the actually-measured rotor rotating speed fluctuation signals and their frequency spectrum analysis outcome are consistent with the results obtained in simulation.So the rotor rotating speed fluctuation signals can indicate rub-impact faults and the degree to which faults occur so as to offer a new diagnosis approach to rub-impact fault.
