Description	In this paper is surveyed the influence of the perturbation using model RK4. The perturbation was induced by centrifugal force. The measurement was made to evaluate influences of the single factors for future including to the mathematical model. There were used various combination of shaft speed and perturbation speed and the vibration spectra were recorded. It was found that the perturbation caused by even a small amplitude of centrifugal force could cause the very dangerous %22oilwhirl vibration%22 even if the amplitude of vibration developed by perturbation itself is low. The simplified mathematical model suggested by Muszynska does not response the situation. This model was not in agreement with measured data. Another mathematical model should be used.
