    Elastohydrodynamic Film Collapse During Rapid Deceleration. Part I—Experimental Results

    , Journal of Tribology, Vol: 123, Pages: 254-261, ISSN: 0742-4787

    <jats:p>This paper describes a study of the behavior of elastohydrodynamic lubricated contacts subjected to rapid halting. Experiments have been carried out using ultrathin interferometry coupled to a high-speed camera to measure the change in lubricant film thickness and shape during fast, controlled deceleration, both in pure sliding and pure rolling conditions. Film collapse is seen to occur in two stages. The first persists throughout the deceleration period and, during this stage the film geometry remains almost constant across the contact. In this stage of film collapse, the film thickness lags behind the value predicted from steady-state theory, which means that when motion ceases, a thicker than expected film is present. The second stage of film collapse ensues when the entrainment speed falls below a critical value of approximately 0.002 m/s and is characterized by the formation of a central entrapment and classical, normal approach, squeeze behavior.</jats:p>

    Elastohydrodynamic Film Collapse During Rapid Deceleration. Part II—Theoretical Analysis and Comparison of Theory and Experiment

    , Journal of Tribology, Vol: 123, Pages: 262-267, ISSN: 0742-4787

    <jats:p>This paper presents a theoretical model for the behavior of elastohydrodynamic films subjected to transient speed conditions, based on Grubin’s analytical solution for elastohydrodynamic lubrication. This model is applied to predict film thickness in high deceleration conditions. The model’s predictions are compared with the experimental results presented in an accompanying paper entitled “Elastohydrodynamic Film Collapse During Rapid Deceleration. Part I: Experimental Results.”</jats:p>

    Elastohydrodynamic film formation at the start-up of the motion

    , Proceedings of the Institution of Mechanical Engineers, Part J: Journal of Engineering Tribology, Vol: 215, Pages: 125-138, ISSN: 1350-6501

    <jats:p> This paper describes an experimental study of elastohydrodynamic (EHD) lubricating film formation during the start-up of motion of a point contact from rest. EHD film thickness was measured using ultra-thin optical interferometry. It was found that film thickness behaviour depends strongly upon acceleration. When motion starts, most lubricants form a front that travels across the contact with its initial thickness unchanged. At some point, depending upon the acceleration, a second front often forms, so that the lubricant film has a characteristic stepped profile. This behaviour occurs in both pure sliding and pure rolling conditions. The development of film profile over time can be used to chart the speed of motion of the fluid film in the contact. In pure rolling conditions, the first film front travels through the conjunction at a speed lower than the entrainment speed in the first half of the contact and higher in the second half. In pure sliding it travels at a velocity higher than the entrainment speed across the whole width of the contact. The leading edge moves as a core of lubricant with a velocity constant through 60 per cent of its thickness. </jats:p><jats:p> At very high accelerations, the central film thickness shows damped oscillations about the steady state final entrainment speed value. These oscillations are similar to those found theoretically by other workers for an accelerated slider bearing using a Navier-Stokes analysis. It is believed that some of the non-classical EHD behaviour observed on start-up may result from the finite rate of momentum transfer across the fluid film. </jats:p>
