Innovative model of radial fluid bearing for simulations of turbocharger rotordynamics

Abstract

The paper describes the principles of an innovative computational model of slide bearing for effective and fast simulations of turbocharger rotordynamics. Theoretical background based on a numerical solution of the Reynolds equation is introduced. The developed simulation tool uses multibody software extended by user-written subroutines and specialized programs developed by authors. The capabilities of the innovative computational models and sample results are demonstrated on a middle size turbocharger rotor supported by fully floating ring bearings.
