Abstract

The asymmetric flexible rotor of turbocharger supported by floating ring bearings is studied. The operating speed of the rotor is 70, 000 rpm. A discrete model of the flexible rotor has been designed. The steady-state mode of the turbocharger rotor is considered. Found rotational speed of 85, 000 rev/min, above which the bearing load capacity is exhausted.
