The objective of this study is to establish an analysis of viscoelastic fluid film lubrication based on nonlinear four-element models, because oils lubricated with a large quantity of high molecular-weight polymers in order to improve the performance of lubricants indicate viscoelasticities as well as non-Newtonian behavior. In the first part of this paper it is made clear from the flow characteristics test that a viscoelastic behavior of such lubricants is expressed by a rheology equation of four-element model which consists of two nonlinear dashpots and two nonlinear springs. The second part applies the theory of Lubrication to parallel circular squeeze bearings, the effects of nonlinear viscoelastic characteristics on the film pressure of parallel circular squeeze bearings are clarified.
