Embodiment Construction
[0041] This embodiment provides the specific implementation process of the present invention in engineering practice.
[0042] 1. Acquisition of rotor displacement and bearing vibration data
[0043] like figure 1 Shown is a schematic diagram of the model of the high-speed rotor bearing system of the present invention (only the vertical direction sensor is drawn in the figure), the structure of the high-speed rotor bearing system is the prior art, and its structure will not be described in detail here; Figure 4 It is a flow chart of the steps of the method of the present invention. The present invention collects the horizontal and vertical direction displacement signals δ of the surface of the counterweight plate through the displacement sensor 1 LH ,δ LV ,δ RH ,δ RV , through the vibration sensor 2 to collect the vibration signal υ of the bearing outer ring LH ,υ LV ,υ RH ,υ RV , collecting the phase signal through the phase detection sensor 3;
