Abstract:
The paper deals with the possibility of obtaining additional information about the state of slide bearing during vibration examination. It is proposed to use the vibrations of slide bearing contact pad as a source of information. 3 Ref., 4 Fig.
Keywords: vibroacoustic measurements, rotor, slide bearing, free oscillation frequency, contact interaction
