Abstract

Misalignment is one of the most influential factors that affect the vibration of a rotor bearing system. This paper presented a combined analytical and experimental approach to investigate the effect of the coupling misalignment on the vibration behavior of a rotor supported by tapered roller bearings. First, a theoretical model was developed to predict the vibration in the rotor system subjected to angular misalignment in the flexible coupling. Then experimental measurements were made from an instrumented test-rig to verify the model. Finally, extended simulations were performed to investigate the effect of misaligned amplitude, rotational speed disk position, bearings distance, and arrangement on the vibration behavior of the rotor. Simulation results showed that the coupling misalignment leads to vibration with multiple harmonics of rotational speed, and that misaligned coupling introduced anisotropic nature in vertical and horizontal vibration responses of the rotor.
