The influence of cutting force on the bearing’s static characteristics depends on the lubrication state of the fluid bearing. In the hydrodynamic lubrication state, the static characteristics can be hardly...

... is stronger. The friction force generated by asperity contact is significantly greater than the water-molecule shear force generated by hydrodynamic lubrication[50], so the bearing system with shaft scratches has a greater friction coefficient. In Fig. 9, the friction coefficients under the two conditions(N=1...
