摘要：
In order to investigate the film pressure distribution of journal bearings using irregular grids, the Reynolds equation was discretized with the cell-centered finite volume method. The least square method was selected to calculate the variable's gradients, and the conjugate gradient method was used to solve the equations. The whole numerical algorithm was programmed with Fortran language and the film pressure was achieved finally. The adaptation and accuracy of the algorithm have been validated by comparison and analysis. The influences of the aspect ratio and eccentricity ratio on the pressure distribution were studied, and the results show that the pressure peak value decreases as the aspect ratio increases and the distribution range of higher pressure is expanded along the axis direction, moreover, the pressure peak value becomes larger as the eccentricity ratio increases. © 2019, Editorial Office of Journal of Vibration and Shock.
