In this paper, we model the oil film bearings and estimate the fluid-induced instability for the design and the diagnosis of the rotating machinery system. The presented model is implemented in our original rotating machinery library by Modelica. An example of a Jeffcott rotor system supported by plain circular journal bearings is simulated. To check the behavior of the model, Campbell diagrams and stability maps are computed by using the Modelica_LinearSystems2 library.
