Abstract
In this paper a “SpectraQuest” demonstrator is used to introduce misalignment in a rotating set-up. The vibrations caused by misalignment are measured by two accelerometers on the bearings and two eddy-current probes on the shaft itself. A comparison is made between the classical spectral analysis, orbitals and full spectra. Orbitals are used to explain the physical interpretation of the vibration caused by misalignment. Full spectra allow to distinguish imbalance from misalignment by looking at the forward and reversed phenomena. This analysis is done for different kinds of misalignment, couplings and combined machinery faults.
