Randomized trial investigates lubrication performance in water-lubricated bearings, suggesting material impacts on cavitation sensitivity.

This research aims to explore how elastic modulus and cavitation affect the lubrication performance of water-lubricated bearings.
A hydrodynamic lubrication model is created considering bushing deformation and surface roughness under JFO boundary conditions.
Three liner materials (thordon, rubber alloy, graphite) are analyzed for lubrication performance under EHL and ML conditions.
Factors like load, radial clearance, and length-to-diameter ratio are systematically examined.
Under EHL, higher elastic modulus leads to smaller elastic deformation and larger cavitation area ratio.
In ML, unusual cavitation behavior with rubber alloy shows a non-monotonic peak under specific conditions.
Increasing load raises water film pressure and friction coefficient, while increasing radial clearance and length-to-diameter ratio generally reduces cavitation area.
