The lubrication characteristics of magnetized journal bearings affected by magnetic fluids considering the elasticity of its liner

In order to investigate the lubrication characteristics of journal bearings with the elasticity of liner affected by magnetic fluids, a theoretic computation model was developed based on magnetic fluids supporting force parameter ((Formula presented.)) and couple-stress factor ((Formula presented.)). The results indicate that maximum dimensionless pressure peak ((Formula presented.)) of oil-film increases with increase in magnetic fluids supporting force parameter ((Formula presented.)), couple-stress factor ((Formula presented.)) and with decrease in elastic deformation coefficient (Ce) of the liner. The loading capacity ((Formula presented.)) increases with increase in (Formula presented.), (Formula presented.) and with decrease in Ce particularly in the high eccentricity ratio (ε); The attitude angle ((Formula presented.)) of S with different (Formula presented.) and (Formula presented.) decreases in a small range of ε at first, and then increases, it increases with the decrease of (Formula presented.) and (Formula presented.), and with the increase of (Formula presented.), theses phenomena are more obvious for (Formula presented.) at low ε and for (Formula presented.) and (Formula presented.) at moderate and high ε; the modified coefficient of friction ((Formula presented.)) decreases with increase in (Formula presented.), (Formula presented.) and with decrease in Ce; the side leakage (Q) decreases with increase in (Formula presented.), with decrease in (Formula presented.) and with increase in Ce particularly in the low (ε). Moreover, the increase of elastic deformation coefficient (Ce) weaken the impacts of (Formula presented.), (Formula presented.) on the increase of (Formula presented.), (Formula presented.), (Formula presented.), and the decrease of (Formula presented.), Q.
