摘要
Influence of 3D surface roughness parameters on performance characteristics of porous journal bearing is studied. The modified form of average Reynolds equation is developed for the porous bearing to include 3D surface roughness effect and its solution is obtained using finite element method. The influence of roughness orientations and roughness characteristics of opposing surfaces on load carrying capacity, coefficient of friction, fluid-film stiffness and damping coefficients of porous journal bearing are studied. Stationary roughness and transverse roughness pattern combination was found to provides maximum enhanced load carrying capacity, fluid-film stiffness and damping coefficients.
