The model treats the bearing as a "canal lock" mechanism and it assumes the competing effects of large pressure gradients across the washer and friction are of the same order. The pressure gradient is assumed to vary sinusoidally in time. The bearing rapidly settles into periodic motion and no breakthrough instability is observed. date: 1990 type: Study Group Report type: NonPeerReviewed format: application/pdf language: en identifier: http://miis.maths.ox.ac.uk/miis/656/1/p7.pdf identifier: King, J.R. and Lacey, A.A. and D., J.N. and S., D.A. and W., P.
