Original abstract

The article describes the development and a subsequent application of the computational tool based on the multibody software for simulation of the turbocharger rotordynamics. The simulation tool is based on the software enabling simulations of multibody dynamics and consists of two basic models which are briefly described in the article. The rotor is modelled as a flexible structure based on the beam nonlinear approach suitable for an effective solution in the time domain. The computational model incorporates journal and axial 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.
