Numerical Simulation of Water-Lubricated Rubber/Chromium Coating Pair Test

The elastohydrodynamic lubrication (EHL) geometric model of the water lubricated rubber bearings under standard experimental conditions with water lubrication was established. The complete numerical solution of the EHL model was obtained by using multi-grid technique. The results show that the EHL state can be only established under high relative velocity and mild load conditions between the rubber block and the chromium coating on steel with sufficient water. The numerical results are good agreement with the experimental data.
