Abstract:In this paper, the identification technique of dynamic characteristics for journal bearings in the field by time series analysis and parameters identification method has been studied. A simplified model of rotor-bearing system is presented and a computer simulative calculation of the tilting-pad bearing is worked out. The results indicate that it is fully in agreement with the theoretical values when damping ratio is small.
Keywords:Sliding bearing  Dynamic characteristics  Parameters  Identification  Field data
