... become significant due to the large surface/volume ratio. Although the velocity slip has been investigated extensively, less attention has been paid on the thermal slip in the EHL regime. In this study, numerical simulations were conducted by applying three cases of boundary slips to surfaces under...

... numerical simulation elastohydrodynamic lubrication Contacting surfaces in mechanical components are important for transmitting power and motion. To reduce the power loss and improve the efficiency and life of mechanical components, the contacting surfaces are usually lubricated [ 1...

...Lin Li; Jinyuan Tang; Yuqin Wen; Caichao Zhu Numerical simulation of three-dimensional rough surfaces based on fast Fourier transform (FFT) is revisited. A more systematic approach, which is an extension of the current FFT-based simulation models, is proposed to approach surface reconstruction...

... as an outcome of numerical simulations. We consider the maximum range of orthogonal shear stress and the maximum shear stress as the critical stress quantities. Forty domains are considered to study the effects of microstructure on the fatigue life of bearings. It is observed that the Weibull slope calculated...

... using numerical simulations and experiments. The quasistatic results of the traction during a single rotation cycle of the roller were averaged, and a deeper understanding of the effects of the groove shape was achieved. The numerical results showed that during a single rotation cycle of the spirally...

... of fatigue lives, the life distribution is obtained as an outcome of numerical simulations. A new critical stress quantity is introduced that considers shear stress acting along internal material planes of weakness. It is found that there is a scatter in the magnitude as well as depth of occurrence...

..., the deterministic numerical solution of mixed lubrication has been extended to evaluate friction between rough surfaces over a wide range of lubrication regimes. The numerical simulation results are compared and agree very well with experiments. The surfaces to be used in the experiment were digitalized...
