Abstract EN

An aerodynamic journal bearing that is capable of self-generating squeeze-film pressure is presented and its dynamic characteristics investigated numerically and experimentally.

A numerical method based on a time-marching static model was applied to assess the orbit trajectory path of the rotor upon a perturbation.

Experimental results were obtained to validate the effect of the self-generated squeeze-film pressure on the stability of the rotor.

Analyzing the Fast Fourier Transform (FFT) responses of the rotor orbits enabled identification of self-excited whirling instabilities.

Both numerical and experimental results showed that increasing the squeeze-film effect of the bearing could raise the threshold speed of instability.
