The paper presents the use of the Teager-Kaiser energy operator (TKEO) to evaluate the state of rotor unbalance. The method was developed in 1990 by Kaiser and involves a simple calculation of signal energy. It has been used before in diagnostics, e.g. during the evaluation of instability of hydrodynamic bearings and as a diagnostic symptom of gearbox damage. This paper is the first to present the use of the Teager-Kaiser method to evaluate the rotor unbalance in hydrodynamic bearings.

W artykule przedstawiono zastosowanie operatora energetycznego Teagera-Kaisera (TKEO) do oceny stanu niewyważenia wirnika. Metoda ta opracowana została w 1990 roku przez Kaisera i polega na prostym obliczeniu energii sygnału. Wykorzystywana była już wcześniej w diagnostyce np. przy ocenie niestabilności łożysk hydrodynamicznych oraz jako symptom diagnostyczny uszkodzenia przekładni. W artykule tym po raz pierwszy przedstawiono możliwość wykorzystania metody Teagera-Kaisera do oceny niewyważenia wirnika pracującego na łożyskach hydrodynamicznych.
