A Review of Tilting Pad Bearing Theory
International Journal of Rotating Machinery, 2011 A theoretical basis for static and dynamic operation of tilting pad journal bearings (TPJBs) has evolved over the last 50 years. Originally demonstrated by Lund using the pad assembly method and a classic Reynolds equation solution, the current state of ...

The use of orbitals and full spectra to identify misalignment [PDF]
, 2014 In this paper, a SpectraQuest demonstrator is used to introduce misalignment in a rotating set-up. The vibrations caused by misalignment is measured with both accelerometers on the bearings and eddy current probes on the shaft itself.
