Original Abstract

The paper presents results of systematic computational and experimental investigations of rotordynamic induced vibrations and noise of turbochargers. The proposed solution approach is based on a combination of a virtual turbocharger and finite element method calculations of structural or acoustic domains. The virtual turbocharger is a computational model enabling simulations of rotordynamics in the time domain by multibody dynamics software. Structural vibrations and emitted noise of the turbocharger are computed by finite element method based on excitation forces calculated by the virtual turbocharger. The solution approach is proposed to rapidly calculate vibroacoustic behaviour of newly designed turbochargers in a development phase. Main results are applied on a turbocharger of diesel engine of heavy-duty vehicle.
