| Abstract: | Based on a rotor-pedestals model with lumped parameters, the paper derives the proportional transfer relationship between bearing and rotor by making use of the mechanical impedance analysis method and elucidates the relationship between transfer ratios and operational stability of bearings. The paper furthermore makes use of these results to analyze the rotor vibration problem of No.1 bearing of Anyang Power Plant's set No.9 and reports that relevant measures were subsequently taken with good results.
