Abstract
The present work numerically and experimentally investigates the impact of bearing misalignment on the rotor-bearing systeminstability. Mathematical models for all novel misaligned bearings are well elaborated. These models are then numerically solved using a finite element C++ bearings program.When simulations are performed, oil pressure and film thickness distribution are plotted and discussed for these bearings.Consequently, different rotors supported on these novel bearings are numerically tested using a finite element C++ rotordynamics program.Misaligned bearings are then designed and manufactured according to the simulations results. These novel bearings are further tested on a 60k rotating shaft test rig.Upon testing these bearings, the oil whip instability threshold is considerably postponed. These results are motive to introduce misaligned bearings in the automotive turbochargers industry
