摘要：
In the analysis of lubrication of rolling cylinders with low modulus coatings, attention is drawn to elastic incompressible layers. The constrained column model (a simplified model where layer compression is assumed proportional to fluid pressure) fails for the Poisson ratio nu of the layers close to 0.5. An approximate lubrication model is proposed for nu = 0.5 and highly deformed coatings, i.e. for the low ratio of elastic layer thickness to fluid film length. This model does not result in a rigid differential equation for high loading as is the case with the constrained column model. The model is applied to the rolling motion of the human ankle joint.
