摘要

The finite difference method is used to solve Reynolds equation and figure up the oil film pressure distribution of hydrodynamic lubrication sliding bearing. The effects of width-to-diameter ratio and eccentricity on the oil film pressure distribution were studied. Bearing capacity of the oil film and offset angle of plain bearing were solved, and the relationship between different width-to-diameter ratio, eccentricity and bearing capacity and offset angle were studied, and the experimental data were consistent with the simulation results, the correctness of the simulation data was verified. This work shows that the numerical calculation method can provide an important mean for the design of the hydrodynamic lubrication sliding bearing.
