摘要:Based on the unbalance response of journal bearings, a dynamic parameter identification model is formulated. Some additional masses attached to the rotor are taken as the applied rotation exciting load of a rotor-bearing system. By extracting the fundamental frequency of the unbalance displacement responses which are processed with harmonic wavelet filtering, the oil-film parameters including the stiffness and damping coefficients can be readily identified by two experiments at the same rotating speed. Experiments indicate that the proposed method has a high identification precision.
