The sediment particles mixed in the lubricant of water-lubricated bearing will make the working environment of the bearing worse and reduce the lubrication performance of the bearing. In order to study the elastohydrodynamic lubrication performance of water-lubricated bearings under the condition of lubrication water containing impurities, the multigrid method was used to analyze the effects of different spindle speed variation forms, impurity particle sizes and shapes on the maximum pressure and minimum film thickness of water film. The results were then compared with that in the pure water lubrication condition. It is shown that sine acceleration and cosine deceleration are the most favorable for the lubrication performance of the bearing among the three speed change conditions of the spindle. The existence of impurity particles will increase the maximum pressure of lubricating water film and decrease the minimum film thickness. The larger the size of the impurity particles, the closer the shape is to the circle, the lower the thickness of the lubricating water film formed, and the greater the pressure. The existence of impurity particles will cause the sudden change of pressure, and bubbles will escape from the water film and form cavitation.
