“…Commonly, the PDF of a random variable 𝛬 is difficult to obtain, but it can be considered as the nominal density function 𝜓(𝛬) with a zero mean and unit variance [38], so the PDF of the variable 𝛬 can be approximated as follows:…”

“…In literature, the non-Gaussian surface generally was applied in the contact analysis [32][33][34][35][36][37]. In hydrodynamic lubrication regime, Li and Zhang et al [38] extended the stochastic methods of Christensen to analyse the non-Gaussian properties effects and investigated the static performance of slider bearing changes with skewness and kurtosis varied. Wang and Liu [39] revealed the fluid load capability of water lubricated tittle thrust pad bearing not only affected by the standard deviation of the surface roughness but also by skewness and kurtosis.…”

“…They found that the bearing capacity is increased effectively and the friction coefficient of bearing is reduced by the surface porous layered structure of lubricating film. Li et al [15] studied the effect of the distribution of surface roughness on the performance of slider bearings, and found that the influence of the skewness and kurtosis on the bearing performance should not be ignored. Wang et al [16,17] studied numerically the lubrication characteristics of textured bearings and non-textured bearings on the basis of the journal misalignment.…”

Generally, the movement of journal along the direction of bearing axis under the combined action of various factors is neglected in the lubrication study of bearing, which is quite different from the actual working condition of bearing in the shaft-bearing system. In this paper, with a comprehensive consideration of the axial movement of journal, the surface topography of journal and bearing and the misalignment of journal, a new model about the hydrodynamic lubrication of misaligned journal bearing is established based on the average Reynolds equation. Considering the effect of the axial movement of misaligned journal, the lubrication characteristics parameters of rough journal bearing is presented and mainly discussed. The results show that the axial movement of misaligned journal has a distinct effect on the bearing lubrication characteristics. The influence of the axial movement of misaligned journal on the bearing lubrication characteristics is slightly reduced when considering the surface roughness.

Abstract:The effects of surface roughness characteristics on the fluid load capacity of tilt pad thrust bearings with water lubrication were studied by the average flow model. The flow factors utilized in the average flow model were simulated with various surface roughness parameters including skewness, kurtosis and the roughness directional pattern. The results indicated that the fluid load capacity was not only affected by the RMS roughness but also by the surface roughness characteristics. The fluid load capacity was dramatically affected by the roughness directional pattern. The skewness had a lower effect than the roughness directional pattern. The kurtosis had no notable effect on the fluid load capacity. It was possible for the fluid load capacity of the tilt pad thrust bearings to be improved by the skewness and roughness direction pattern control.
