论文简介如下:

This paper investigates journal bearings, and builds a lubrication model taking into account misalignment, the lubricant couple stress e?ect and shear thinning. In order to explore the sensitivity of couple stress ?uid lubrication performance to oil flm thickness, we introduce the critical oil flm thickness coefcient. The results show that the sensitivity increases with the increase of the couple stress coefcient, and it is highest in the area of minimum oil flm thickness. Compared with a parallel journal, increases in the misalignment angle strengthen the e?ect of couple stress. Shear thinning also plays an important role in bearing lubrication performance. For a low oil inlet temperature, the e?ect of shear thinning increases with the increase of the couple stress parameter. For a high oil inlet temperature, the in?uence is negligible. An increase in the misalignment angle will not further enhance the e?ect of shear thinning.
