Paper Title:
Identification of the Dynamic Coefficients of Hybrid Bearings
  Abstract

Within the linear region, the oil-film force increment of journal bearing is a fourdegree- of-freedom linear system. This paper presents an experimental method to identify hybrid bearing coefficients. Under various testing conditions described, experimental data are required on a complex test rig. An inverse technique based on least square method in time domain is developped for the coefficients identification. It results from the experimental data exploitation that the linear stiffness and damping coefficients are sensitive to the pressure feed, but the mass coefficients are insensitive.
