... complicated. In this work, thermal elastohydrodynamic lubrication (EHL) numerical calculation is carried out under the condition of periodic impact and opposite sliding line contact over a wide range of surface speeds. The pressure is solved by a multigrid method, the elastic deformation is evaluated using...

...Hiroyuki Ohta; Daisuke Matsuyama This paper deals with rolling traction in isoviscous-rigid (IVR), piezoviscous-rigid (PVR), and elastohydrodynamic lubrication (EHL) regimes at line contact. First, a measuring method of rolling traction using the two-disk machine supported by ball bearings...

...Huaiju Liu; Ken Mao; Caichao Zhu; Xiangyang Xu The unified approach based upon the Reduced Reynolds technique is applied to develop a deterministic transient mixed lubrication line contact model. This model is used in spur gear applications to comprehensively show effects of roughness, working...

...Dong Zhu; Jiaxu Wang; Ning Ren; Q. Jane Wang Concentrated (or counterformal) contacts are found in many mechanical components that transmit significant power. Traditionally, concentrated contacts can be roughly categorized to point and line contacts. In point contacts, the contact area is small...

...M. Masjedi; M. M. Khonsari Three formulas are derived for predicting the central and the minimum film thickness as well as the asperity load ratio in line-contact EHL with provision for surface roughness. These expressions are based on the simultaneous solution to the modified Reynolds equation...

... of these variations on the subsurface stress field in Hertzian line contacts is studied. Fatigue life is formulated as a function of a critical stress quantity and its corresponding depth, following a similar approach to the Lundberg–Palmgren theory. However, instead of explicitly assuming a Weibull distribution...
