Original Abstract

The article describes the computational model of turbocharger rotor including slide bearings and a subsequent application of multibody software for simulation of the turbocharger rotordynamics. The new developed simulation tool is based on the software enabling simulations of multibody nonlinear transient dynamics. The rotor is modelled as a flexible structure based on the Timoshenko’s beam nonlinear theory suitable for an effective solution in the time domain. The computational model incorporates journal and axial slide bearing models. Theoretical background of the journal bearing computational models, based on the numerical solution of the Reynolds equation, is presented. The simulation capabilities and possible results are demonstrated on the tractor diesel engine turbocharger rotor supported by fully floating ring bearings.
