Abstract
Considering small pressure change in the gas film of hydrodynamic gas-lubricated journal bearings, the corresponding nonlinear Reynolds equation is linearized through appropriate approximation and approximate Reynolds equation is derived and solved by means of finite difference method (FDM). The gas film pressure distribution of hydrodynamic gas-lubricated journal bearing is attained and load capacity is calculated. The approximate numerical solution shows better agreement with experimental data than direct numerical solution and demands less computer time. It is of interest to note the eccentricity ratio ε at which approximate numerical solution is better agreement with experimental data is different when bearing number is changing. The approximate numerical solution is slightly larger when the eccentricity ratio is smaller, and becomes slightly smaller when the eccentricity ratio is larger.
