Tribologische Beurteilung des Verschleiβverhaltens der kolbenbolzenlagerung

Even with simplifying assumptions, the quantification of frictional and wear processes in high-speed engine systems is extremely complex. Reliable distribution) must be determined at the microcontact. Moreover, real surfaces always exhibit inhomogeneities in the final machined condition. For an accurate determination of friction and wear values, a realistic simulation of the relationship between load and stress in an absolute prerequisite. The determination of friction and wear values is highly dependent on the extent to which the relationship between load and stress can be simulated realistically. Consequently, basic experimental investigations of tribosystems subjects to mixed friction are recommended for determining the real wear values. Results of wear and motion measurements on the piston pin bearing are presented. The load-bearing performance of the bearing is determined by simulation of the lubrication conditions.
