Abstract:

A model of elastohydrodynamic line contacts under grease lubrication with solid particles is established,and the corresponding lubrication equations are deduced. Then,the film pressure and thickness affected by the coordinate,dimension and velocity of solid particles are numerically analyzed and are compared with those without solid particles. Numerical analysis results show that the presence of solid particles has a certain influence on the
film pressure and thickness,that sphere solid particles significantly influence the film pressure and thickness,especially the radius of sphere particles,and that flake-shape solid particles only have slight influence on the film pressure and thickness.

Key words: solid particle, grease, elastohydrodynamic lubrication, lubrication equation, numerical analysis
