The paper introduces a multibody based computational model of the turbocharger rotor proposed for simulations of structural transient dynamics. Computational models of rotor components, fully floating ring radial bearings and thrust bearings are briefly introduced. The computational model of the turbocharger rotor is designed to allow an efficient solution to a rotor movement while retaining its highlevel capability to describe the rotor dynamics and bearing tribology. The results help understand the vibration and noise issues of turbochargers. The computational models are verified using technical experiments on diesel engine turbochargers.
