Considering the surface roughness of piston ring and cylinder liner and deformation of cylinder liner, the friction dynamics calculation model of cylinder liner-piston ring friction pair was established. The effects of top ring, other piston rings and cylinder liner surface roughness on friction performance were analyzed by grouping comparison and Box-Behnken response surface methodology. The calculation results show that when the surface roughness of the piston ring increases, the friction of the asperity increases slightly, the friction of the fluid decreases, and the total friction loss decreases. When the surface roughness of the cylinder liner increases, the friction of the asperity decreases slightly, the friction of the fluid increases, and the total friction loss increases.
Key words: Piston ring / cylinder liner / surface roughness / response surface analysis / friction performance
